A capacitor is an electrical component, which sto-res electric charge. Its most important application is that of power factor correction (see Reactive compensation chapter).

The capacitive element’s constructive material de-pends on its application. RTR Energía S.L. manu-factures cylindrical capacitors with propylene film, metallized with elements such as Al o Zn, which makes it self-healing and reduces the possible losses. This film will have different thicknesses depending on the working voltage. The elements used for metallizing act as current conductors, and the polypropylene as a dielectric.

After the manufacturing process and a quality con-trol, the capacitive elements (coils) are introduced in aluminium or plastic cans, and then encapsu-lated with polyurethane resin, which is ecological and non-toxic. This resin is specially designed by the RTR Energía S.L.’s Chemistry Department and can be used with different capacitors and electric equipments which need encapsulation.

ANOTHER TyPE OF CAPACITOR

• MICA capacitors: used as high frequency and telecommunication capacitors.

• CERAMIC capacitors: used in telecommunica-tion applications when there is not enough spa-ce.

• ELECTROLYTIC capacitors: used mainly for di-rectcurrent rectifications.

• TRIM capacitors: their capacitance can be modi-fied depending on the needs of the application.

General Information

11

CA

PACIT

ORS

A capacitor is used for storing electrical energy. The capacitor is charged when the capacitor’s pla-tes voltage, Uc, levels up with the supply voltage, Uca.

The movement of the electrons in between the plates of the capacitor constitutes the electrical capacitive current Ic, which flows through the line and provides electric energy to the capacitor, ge-nerating an electric field between the capacitor’s plates.

If Ic is released, the electrical energy remains sto-red in the electric field, and so, in the capacitor.

CAPACITOR´S CHARGE

The number of electrons which are moving during the charge of the capacitor (Q), measured in Cou-lombs (C) which are dimensionally equivalent to amperes times second (A·s). The charge is the amount of electricity stored in the capacitor.

Once the capacitor is charged, this charge is main-tained even when the outer electrical energy is dis-connected, as the attractive force between plates is also maintained, due to the polarity difference between them.

Because of this, the capacitors have a discharge resistor in their terminals so the discharge in the capacitor can be avoided when an operator is han-dling it.

This resistor must meet the standard UNE EN-60831-1-2 in its 22th chapter for three-phase power capacitors and the standard UNE-EN-61048-49 for lighting capacitors.

Voltage is very influential in the behaviour of the capacitor, thus the charge fluctuates with it. Char-ge (Q) Supply voltage (U) ratio is a constant value, which depends on the capacitor’s frame and is de-noted as capacitance (C), measured in Farads (F).

A capacitor has a 1 Farad capacitance when it stores a charge of 1 Coulomb if a 1 V voltage is applied between the plates.

Keeping the basic principle of capacitor’s de-pendence, which states that the bigger it is the area of the plates, the bigger it is also the capa-citance, and in the other way, the bigger it is the distance between these plates (dielectric’s thick-ness) the lower it is the capacitance. Due to this principle, electric-field intensity (E) can be defined in a capacitor as:

DIELECTRIC AND REGENERATION

Electrical capacitors use nowadays dielectrics made of propylene film, metallized with elements such as Al or Zn, among others, with different thic-knesses depending on the applied voltage bet-ween the plates.

As it was seen before with the basic principle of dependence, the lower it is the dielectric thickness, the bigger it is the electric-field intensity, which provokes that the size of the capacitors is gradua-lly smaller, as they have for distances between the plates the thickness of the film, in micron.

214 4Depending on the values of the constants of every

dielectric, there is a limit potential difference, which all materials can manage throughout the thick-ness. This limit is defined as electrical stiffness.

Because of determined electric-power system conditions or extreme temperatures, inadmissible for the correct working of the capacitor, this volta-ge limit can be overfilled. Thus, the dielectric can be bored and an electric arc will be formed bet-ween the plates.

The propylene film self-healing means that the electric arc will not generate a short circuit, but will evaporate the metal which surrounds the breakthrough point. This way, the isolation bet-ween plates is repaired in the latter breakthrough point.

After this self-healing, the capacitor can work in normal conditions, with a capacitance leak inferior to 100 pF.

DIRECT VOLTAGE

When a capacitor is connected to a continuous voltage, Ucc, the current has a very high intensi-ty and is limited by the ohmic resistance, which is tiny in the capacitor. When the voltage between the plates of the capacitor increases, the current gradually decreases.

When the charging process is finished, the current intensity becomes zero. In continuous rating and direct voltage, the capacitor behaves as an open circuit.

During the discharge process of the capacitor, the voltage and the current decrease with the same ratio, and so they become zero simultaneously.

The charge and discharge time is directly propor-tional to capacitance and circuit resistance, and so, when the resistance fluctuates the charge and discharge process can be shortened or extended.

The time constant t, is the time needed by a capa-citor to gain a 63% of the charge of the impressed voltage, and is denoted as:

In theory, the total capacitor’s charge or dischar-ge is produced after an infinite interval of time, as the mathematical function which defines it attains the limit in an asymptotic way. But in practice, the capacitor is charged or discharged in a 5-times in-terval.

ALTERNATING VOLTAGE

When a capacitor is connected to an alternating voltage, the plates are positively and negatively charged, in an alternating and periodic way, with a flow of alternating current.

The capacitor is periodically charged and dischar-ged, and so the two processes are simultaneous, because of the alternating current flowing through the network. This periodical process provokes an inversion in the direction of the current when this current’s value is zero. In the same way as in di-rect current, the capacitor acts as a finite resistan-ce, measured in ohms:

When the current’s value is zero, the charge pro-cess in the capacitor is finished as it will be totally charged at the end of the positive half-wave of the current for a known value of voltage, +Uca, and at the end of the negative half-wave with a voltage value of -Uca.

The discharge process is produced when the cu-rrent reaches its maximum value, therefore, the voltage value tends to be zero.

Voltage influence in capacitors

The complete charging and dischar-ging process is done in an electrical voltage semi period. If the electrical voltage’s period in Europe is 20 mili-seconds, a capacitor will need half of this time for completing its charge or discharge.

A single-phase capacitor is that which can be im-planted between two phases or between phase and neutral.

The reactive power of the capacitor (Q) is measu-red in VAr, and defined as:

440 V VOLTAGE

Due to the importance of the supply voltage on the reactive capacitor’s power, there is a need of knowing why the nearly totality of capacitors ma-nufacturers, included RTR Energía S.L., design their capacitors for a 440 V voltage.

With this design, the capacitor’s reliability and life increase because it warrants that it will resist an overvoltage that can be produced in the power lead, and that, as it is said in the standard UNE-EN-50160, it can be up to a 10%.

Single-phase capacitors

The content of the standard UNE-EN-60831-1/2 says that, for indus-trial frequencies, a capacitor must exist a voltage value of 1,10·Uca (440 V), at least 8 hours a day.

These capacitors are designed for being connec-ted to a three-phase electric line, R-S-T, and the way of connecting the capacitive elements (coils) in its interior is with two possibilities.

DELTA CONEXION

The total capacitance of the capacitor is divided in three partial capacitances C

D, as shown in the

diagram.

If the capacitance between two phases is taped, for example R-S, the total capacitance will not be the C

D of the RS phases but the C

D(RS) in para-

llel with the series connection CD(RT)-C

D(ST) (see

section G), which means:

Now, the reactive power in the capacitor (Q) can be defined, as well as its capacitive current (Ic).

STAR CONNECTION

This connection scheme is not so usual, and is used when the line voltage is higher than the one that can be allowed by each of the wirings, as:

The Ic is defined in the same way that it is done in the delta connection, while the reactive power is:

PARALLEL

In the parallel connection between capacitors, the global equivalent capacitance is the sum of the ca-pacitances. The same occurs with the total reacti-ve energy.

The impressed voltage between the capacitor’s plates is the one that can be allowed depending on the capacitor’s constructive characteristics. All the capacitors are affected by the same voltage.

SERIES

When the working voltage, Uca, is higher than the rated voltage on the manufactured capacitor, a group of capacitors can be connected in series. In this case, every capacitor will have a different voltage between plates, depending on its capaci-tance and reactive power. As every series connec-tion, the current flowing through them is the same for every capacitor.

The inverse of the total capacitance (CT) is the sum of the inverses of the different capacitances.

The reactive power (QT) has the same behaviour as the capacitance, thus the inverse of the total reactive is the sum of the inverses of the different reactives.

The leakage tangent of a capacitor (tan d ) is the value that can define the quality and behaviour of an electrical capacitor. The leakages in a capaci-tor can be related and represented throughout the losses of an ohmic resistance (R).

Considering an ideal capacitor, without losses, the angle of phase difference j between the current Ic and the voltage Uca is 90º.

This is an ideal situation, but in fact every capaci-tor has losses because of the propylene film, the plates’ metallization, the solders, wires, etc.

Due to these losses, the angle of phase difference, j , is not of 90º, and the voltage, Uca, is lagging with respect to the active current, Iactive, and the new an-gle formed is the loss angle, defined as j = 90º- d . Its tangent is the leakage tangent of the capacitor.

The loss power (Pp) of a capacitor, measured in watts (W), is:

The capacitance of a capacitor is reduced with its lifetime, which increases gradually the capacitor’s losses, due to the inverse ratio of the leakage tan-gent and the capacitance.

Leakage Capacitor’s Tangent

RTR Energía S.L. priori-tizes its product’s quality by using the best metalli-zed film, manufactured in European Union.

The quality process gua-rantees that the losses power of the capacitors is inferior to 0.5 W/kVAr,

When handling a capacitor, there is a need of ta-king into account a series of security precautions. When a capacitor is disconnected off the voltage, it remains charged with the supply voltage. If the plates are shorten and touched, they can cause a dangerous accident due to the violent discharge of the capacitor.

The standards EN-61048 and EN-60252 establish the need of the capacitors of having illumination and a discharge resistor’s motor, so that when the supply voltage is switched off, it must store a maxi-mum voltage of 50V in an interval of 60 seconds.

In the same way, the three-phase capacitors must be equipped with a snubber resistor, which can discharge voltage until its maximum value is 75V in an interval of 3 minutes, as it is stablished in the annexe B of the standard EN-60831-1/2.

DISCONNECTION SySTEM

Due to extreme and inadmissible operating con-ditions of overvoltage, overcurrent or high tem-peratures, RTR Energía S.L. has designed an overpressure release system, which works by unpacking the terminal covers, thus the terminal connection with the capacitive element is interrup-ted.

Under this conditions and seeking a right perfor-mance of the release system, it is very important that the resin of the enclosure is designed to avoid that the metal fusion’s gases are entrapped. It must allow these gases to rise, and so the system will work accurately. Because of this, RTR Energía S.L. has a Chemical division which develops and manufactures the electrical resins, depending on each of the applications.

The capacitors must operate under the following limits:

This means that a capacitor must never reach a value beyond 55 ºC, or remain more than 24 hours beyond 45 ºC or more than a year beyond 35 ºC of temperature.

The maximum current that a capacitor can reach is 1,5 the rated current, (1,5 · In).

Electric power can be defined as “the capability of an electric equipment of doing a mechanical work, or the work quantity that can be obtained in a de-termined amount of time”

It is measured in watts (W), and its most frequent multiples are the kilowatt (kW) and the megawatt (MW), while the most used submultiple is the mi-liwatt (mW).

However, in AC power supply equipments which running is based in electromagnetism, such as transformers, motors, etc, by generating their own magnetic field, there are three different types of power coexisting:

• Active power (P)• Reative power (Q)• Apparent power (S)

These three different types of power can be rela-ted by a power-triangle. There is an angle, •, for-med by the apparent and the active powers, which defines the out-of-phase between the voltage (U) and the current (I), and its cosine of this phase an-gle is equivalent to the line power factor (PF) when there is no harmonic distortion.

POWER FACTOR (FP)

The power factor (FP) is the ratio of active power (P) to the apparent power (S) and is determined by the kind of loads connected to the installation, where the resistive loads have a power factor clo-se to unity. When inductive and reactive loads are introduced, power factor can vary by leading and lagging the current with respect to the voltage.

This out-of-phase can measure the power factor.

ACTIVE POWER (P)

Active power represents the real power, measured in watts (W). Thus, the amount of energy used when an electric equipment is functioning and working, i.e. the energy given by a motor shaft when moving a device, the energy given, in terms of heat, by an electric heater resistance, or the light given by a lamp, etc.

Active power is also the hired power to the electric company, and can reach households, industries, offi-ces or any other facility when it is needed, along the supply network. The global amount of power, used by the totality of electric appliances is normally registered by counters or other electrical meters, which are installed by the deliverer companies in order to measure the totality of electric energy consumed in a particular period of time, specified in contracts.

REACTIVE POWER (Q)

Reactive power is the power consumed by motors, transformers or any other electric device including any kind of coil, so that it creates an electromagnetic field. These coils are part of an electric circuit, and in electric systems they constitute loads, consuming both active and reactive power. Their work efficien-cy depends on their power factor; the lower it is (far-off unitiy) the bigger is the amount of reactive power consumed. Besides, reactive power does not produce any effective power and produces a negative im-pact on the energy transmission through the distributing electric lines, thus its consumption is penalized throughout the tariff by the mains supply company. Reactive power is measured by volt-ampere reactive (VAr), and its most frequent multiple is the kilovoltampere (kVAr).

APPARENT POWER (S)

Apparent power or gross power is, according to the Pythagoras theorem, is the active and reactive power sum. These two components represent the total line input power, also the totality of the power given by the electric generators in the set. This power is imparted along distribution cables, also lines, reaching consumers in households, factories, industrial plants, etc. Apparent power is measured in volt-ampere (VA).

LOSSES INCREMENT IN CONDUCTORS

• Conductor heating accelerates the isolation da-mage, reducing its lifetime and producing possi-ble shortcircuits.

• Capacity droop on the National Electrical Net-work, when generating an extra amount of ener-gy, due to loss compensation.

• Winding heating in transformers. -Resist drop-outs without an apparent cause.

GENERATORS AND TRANSFORMERS OVERLOAD

A current excess because of a low power factor can induce generators and transformers become over-loaded, reducing therefore their useful lives when overrunning their design ratings.

POTENTIAL DROP GROWTH

Current flowing through an electric conductor produces a potential drop, which is defined by Ohm’s Law.

The current growth because of a low power factor will produce a bigger potential drop, causing an in-sufficient power supply in loads requirement, reducing, thus reducing in them the output power.

POTENTIAL DROP DECREMENT ON DISTRIBUTION LINES

The current must overcome the conductor’s electric impedance (Z) while the electric energy is being transported, therefore a potential drop is produced.

Potential drop can be determined by Ohm’s law, and is the product of current and resistance. If the value of the demanded current is substituted by its equivalent in terms of line power, the following expression is obtained:

Reactive Energy Compensation’s Benefits

CAPACITy GAIN ON THE ELECTRIC LINE

If the power factor were compensated, part of the extra power, produced in order to reduce losses, could be used in the electrical provided consumption. Checking out the consumption and losses profiles, the Spanish National Electrical Distributor could gain a 0,5% in capacity, enough energy for more than a twoyear Ceuta and Melilla supply.

Reactive power compensation is good not only as a technical advantage but also as an eco-nomical one.

Since January 2012, companies in Spain with an electrical contract of 15kW or more (basica-lly, every commercial enterprise from a small store up to a big industry) can be suffering bursts in their billing, because of a legal chan-ge published in BOE, on December 31, 2009, which tries to actuate on energetic efficiency throughout a more responsible use of energy in companies.

Reactive energy compensation is achieved by the installation, in electric lines, of capacitor banks, which can generate capacitive loads, so that reactive losses in the wiring are reduced.

With these new rates, any industrial plant which has basic equipment, such as furnaces or fluo-rescent lamps (see charts in section A), can suffer charge build-ups due to reactive energy.

This amendment means to users which, until now did not pay any reactive energy consump-tion, are suffering, since January 2010, a burst on their electrical billing.

Obviously, this new legislation is specially affecting industrial plants which use trans-formers, motors and any other industrial receptor that needs magnetic fields for run-ning.

Value determination

In order to determine the power factor for its co-rrection, a three-step method is used, which can be followed in the attached block diagram:

1. Installation’s reactive power computation 2. Capacitive power, needed to compensate, com-

putation 3. Installation’s power factor (FP) variability com-

putation

REACTIVE ENERGy COMPUTATION

The installation’s reactive power calculation im-plies determining its power factor (FP). Therefore, the facility needs to be studied with, among other equipment:

• An electric line analyser • An energy consumption bills analysis, as shown

in the block diagram.

CAPACITIVE POWER COMPUTATION

Once the installation’s FP is determined, the value of the desired power factor (which will totally re-move reactive energy), FPdesired, must be selected. This value is going as close to unity as possible.

There is a value, named “k factor”, which is de-fined by the tangent’s difference, and its most fre-quent values are listed in the table below.

Once the k and F values have both been defi-ned and calculated, the capacitive power (PkVAr), in kVAr, needed for the FP compensation, can be calculated too. RTR Energía S.L. suggests an in-crease of 15-20% of the PkVAr value, in order to fo-recast any other capacity increments.

POWER FACTOR’S VARIABILITy COMPUTATION

If a central compensation scheme is chosen (see section F), the fluctuation pattern of the FP with time must be known, in order to decide the number of steps needed by the bank for achieving the calculated capacitive power throughout time.

For example, assuming an 80 kVAr battery is needed, and knowing that 60 kVAr are produced by a fixed motor, the re-maining 20 kVAr can appear and disappear intermittently du-ring the day.

INDIVIDUAL COMPENSATION

Individual compensation is used in continuous working cycle equipments, where reactive consumption is significant, mainly in electric motors and transformers. The capacitor is installed in every single load, so the only conductors affected by the reactive energy are those who are uniting load and capacitor. This configuration has, on the one hand, the following advantages:

• Reactive energy is confined between load and capacitor. Therefore, the remaining lines are free from this reactive energy.

• The capacitor is switched on only when there is a connected load, as the starter functions as the capacitor’s switch so no other control system is needed.

On the other hand, this configuration has the following disadvantages: • Individual capacitor’s price is higher than that of an equivalent capacitor on its own. • Capacitor’s are under-used when an individual load remains idle for a long period of time.

This fixed-compensation configuration has to be studied carefully when any of the following highlighted cases: in asynchronous motor’s compensation and power transformers (see section G).

GROUP COMPENSATION

The group-compensation configuration is sugges-ted when a group of loads (either different or not) are simultaneously connected, thus demanding a constant amount of reactive energy.

This configuration has, on the one hand, the fo-llowing advantages:

• The capacitors bank can be put in where motors control centre.

• Capacitors are only used when the loads are working

• It has a lower set-up cost. • Reactive power is totally removed from distribu-

tion lines.

There is, on the other hand, a disadvantage on the main power lead: there is still reactive power remaining between loads and the motors control centre

CENTRALIZED COMPENSATION

The total capacitor’s bank power is installed (put in) on the tapping, next to the energy feedboards. The total bank power is divided between a num-ber of packs or steps, put through with an auto-matic controller which can switch them on and off when wanted, depending on the instant reactive consumption. This configuration has, on the one hand, the following advantages:

• More efficient use of capacitor’s capacity. • Better voltage regulation in electric systems. • Bank’s power output adjusts according to any gi-

ven instant requirement

On the other hand, the shortcoming of this confi-guration is that power distribution lines are not re-lieved from reactive power, and still an automatic controller is needed in the setup.

MOTOR

ASyCHRONOUS THREE-PHASE MOTOR’S DIRECT STARTING

When compensating individual asynchronous mo-tors, care must be taken in order to avoid self-exci-tation appearance. Self-excitation begins when the motor is turned off, as it remains spinning because of the inertia, until it finally stops. When the feed is cut out, if the compensation has been done on the motor’s terminals then the capacitor’s capaciti-ve currents on the stator will generate a magnetic field on the rotor in the same direction as the de-creasing magnetic field. Thus, the motor will work as a generator, and this will cause overvoltages in the motor terminals.

There are two possible solutions in order to avoid self-excitation appearance:

• Capacitor’s capacitive currents can be limited through the capacitor bank power’s limitation so that they are lower than the motor’s void current (EN60831-1 standard advices that void current should never be higher than the 90% reactive void motor’s power).

• Compensation can be done in terminals throug-hout a contactor. This way, when the motor is turned off from the feed, capacitors will remain insulated from the motor terminals.

WyE-DELTA STARTER

Sometimes the direct asynchronous motor’s con-nection is not possible, normally because of the current peaks that appear during the starting (start). When this occurs, wye-delta commutators are used.

If the motor is fitted with a wye-delta starter, the capacitor’s connection will be done with connec-tors, so that the capacitor will be switched when the motor has finished its start (wye) and has achieved a continuous rating.

Using this starting method avoids overcurrents and overvoltages during motor starting.

POWER TRANSFORMERS

Transformers reactive energy compensation must be enough to rectify the reactive energy that can appear during its void working, as this is a cons-tant value (Q0) and also the absorbed reactive energy when charged.

RTR Energía S.L. power capacitors are manufactured under a strict Quality Control that verifies the capacitor’s correct working in every production line. In order to obtain the best capacitor’s performance it is very convenient to follow the installation suggestions, supplied with every capacitor.

SWITCHGEARS

They should be, preferably suitable for sudden breakdown, and dimensioned for a 1.6 to 2 times the rated capacitor’s current.

FUSES

As switchgears, they should be suitable for sudden breakdown and able to manage the high charge and discharge current capacitor’s values. So, their calibration must be done between 1.6 and 2 times the capacitor’s rated one.

CONDUCTORS

For the same reasons as exposited before, the minimum wire section must be 1.8 times bigger than that used for rate current.

TEMPERATURE

Ambient temperature for a satisfactory capacitors working should be within -25º C and 55º C. Because of this, if there were reactances placed in the setup, capacitors should be located below them, in venti-lated and air-conditioned areas if needed.

Quality, Installation and Protection

RTR Energía S.L. seeks to maintain conti-nuous improvement, and has been awar-ded the certification of its Quality Assurance System under ISO 9001: 2008 by AENOR and IQNet.

Never manipulate charged ca-pacitors. Before touching a ca-pacitor, even when discharge resistors have been fitted, the capacitor terminals should be short-circuited and grounded.

An example of a real-life case of power factor com-pensation in a hostelry-place is presented here. The installation has a 40 kW demand and a monthly bill of €1468,66 of the consumed energy plus 420,42 of reac-tive energy. Therefore, if reactive energy is compensa-ted, the billing will be reduced in a 28%.

The power consumption statistics shown below divides the customer’s power bill in 6 day-intervals. For each period, the active and reactive powers and the peak de-mand (peak demand meter reading) are shown.

GLOBAL COMPENSATION COMPUTING

Following the calculation steps shown in schedule E, and considering the hired power as F’s value, the installation’s power factor can be determined, as well as the capacitive power needed for the reactive energy compensation.

STEPS CALCULATION

Always following the procedure shown in Schedule E for each of the time periods, and taking F as the corres-ponding peak demand meter reading, the power factor and needed capacitive power can be we can determi-ned for each of the intervals.

Case Study: Commercial Establishment

Thus, the capacitors bank power should be of, at least, 37.5 kVAr.

RTR Energía S.L. advices an increase of this value of 15-20%, in order to sa-tisfy future power demand increments. So, the chosen capacitor bank in this case would be a mural-series one, precisely a 45kVAr one, with 5 steps (1x5+4x10).

The minimural-series would not be sui-table in this case, as it only has three steps (3x15).

Reactive power compensation offers the following advantages:

INCREASE OF ENERGY USAGE EFFICIENCY by reducing transport losses. When losses are redu-ced, there is no need of producing an extra amount of energy, in order to compensate these losses. Thus, the greenhouse gasses emitted when electric energy is generated are also reduced.

INCREASE OF THE NATIONAL GRID’S CAPACITY, since the energy, generated as an extra due to compensate losses can be used as consumption energy. Based on power consumption and losses statistics, the Spanish National Grid’s capacity would increase by 0.5%, energy enough to supply, for example, more than twice the yearly consumption of Ceuta and Melilla.

OPTIMIZATION OF THE INSTALLATION DESIGN as the increment of the conductor’s size is preven-ted even though the current is increasing. Therefore, resources such as copper, which has an important influence in the installation’s budgets, are used in a more efficient way.

INCREASE OF THE ELECTRICAL MACHINE’S DURABILITY. The reactive energy removal provokes a current’s growth, which is responsible for a reduction of the power appliances useful lifes.

INCREASE OF THE ELECTRICITY SUPPLY QUALITY by reducing the increment in power drops during its transport. This voltage drop is responsible for the decreased output power in loads, such as motors, lamps, etc.

ECONOMICAL SAVING in electrical billing, obtained by removing the reactive energy consumption penalties. This penalties may nowadays mean a 30% of the total power bill.

ICS Quality of Electric Energy

The basic fundamental parameters which define an electrical energy supply are: supply voltage (U) and current (I).

The right voltage supply (U) and the ability for gi-ving users the amount of needed energy in a par-ticular moment depends on the electricity supplier company, which distributes the energy.

In Spain, voltage is supplied at 400 volts (V) in a three-phase system, with a frequency value of 50Hz, considering this as low voltage up to 1000V. From 1000V up to 25 kilovolts (kV) it is considered as medium voltage, which depends on the areas and the supply companies.

Finally, values over 25 kV are considered high voltage, and it is used basically for transporting electrical energy in large distances.

Actually, QUALITY (correct energy supply) and ELECTRIC ENERGY EFFICIENCY (obtaining the maximum yield out of it) concepts must be unified. Because of this, the maximum consumption of energy must be optimized, as well as its transport and use. This will grant the correct running of the electrical equipment.

The most important characteristic in quality and energetic efficiency is that of generating and trans-porting the maximum amount of active energy, which produces effective power. This compensates the oscillating energy loads, as well as the nonproductive ones, as reactive energy (see chapter of reac-tive energy compensation) or distortion energy, produced by some of the electrical appliances with nonlinear components, such as non-filtered reactances, speed shifters, rectifiers or electronic starters, among many other.

Negative quality aspects of the electri-cal supply, as established in the standard EN-UNE-60150:1996, are:

• Overvoltage • Electric Power Interruptions • Cutoffs • Voltage fluctuations • Flicker • Voltage holes

ICSElectrical Network Disturbances

With the aforesaid standard, UNE-EN-60150, here are some of the most important electrical network disturbances.

FREQUENCy VARIATIONS

Frequency disturbances measured in 10 seconds avera-ge values. These variations produce an inaccurate run-ning in electric motors, both synchronous and asynchro-nous, electrical household appliances, etc.

UNBALANCED THREE-PHASE POWER SySTEM

The voltage or current three-phase system is perfectly ba-lanced when its three phases (R, S and T) have a 120º angular displacement between them, and when its vector modulus have the same value.

If the system is unbalanced, it can occur that the modulus of each of the different phases are different, or that the phase shift between two of the vectors is not the usual value of 120º. Furthermore, these two things can happen simultaneously.

Displaying a three-phase system this way, either balanced or unbalanced is valid if the system has three wires or four, including the neutral wire.

The unbalanced systems must not exceed the following values:

Current < 10% Voltage < 3%

When the system is unbalanced, the current through the neutral wire increases.

Harmonics

Harmonic voltage is defined by the standard UNEEN-60150:1996 as “a sinusoidal voltage, where the frequency is an integer multiple of the system’s supply voltage fundamental frequency”.

Fourier, a French mathematician, defined this phenomenon by the following assertion: “any pe-riodic signal, no matter its complexity, can be split in a number of signals, and the sum of these sig-nals will have a frequency which will be a multiple of the fundamental or reference frequency”

After analysing this phenomenon, the conclusion in RTR ENRGIA S.L. is that this is the most accu-rate definition for a harmonic, though the Fourier’s mathematic series expansion is not going to be studied here, as it is not part of the purpose of this handbook.

Harmonics generate non-linear loads. These loads, when connected to a sinusoidal and alter-nating electrical network, absorb non-linear cu-rrents. Their amplitude and frequency depends on the current’s wave distortion when a sine voltage is applied to them. These non-linear loads are ge-nerally periodic.

HARMONICS ORIGIN

Among many others, the main causes of the harmonic distortion are the following.

• Electromagnetic and electronic lighting ballasts • Electric welding equipment • Single-phase network connected electronic equipment • Electromagnetic reactance for discharge lamps • Electronic starter • Speed shifters

HARMONICS EFFECTS ON ELECTRICAL NETWORK

• Increase of transported power, worsening the network power factor • Automatic switch untimely drop-out • Conductors overloads • Vibrations and overloads in machinery • Establishment of instabilities in electrical systems • Wrong operation of protective relays • Capacitors’ impedance fall-off ( Xc ) = 1/• · C. This may produce a failure in the automatic regulated ba-

ttery, which is installed in order to rectify the power factor when the resonant phenomenon appears (XL=Xc). This situation is explained in detail in section D.

• Wrong measures in measurement apparatus • Noises in control equipment

The electrical companies analyse the penalties to be applied to industrial installations which generate harmonics, as well as to the ones which generate reactive energy.

ICSHarmonics Parameters

Harmonics can be classified by three different parameters: order, frequency and sequence, which can perfectly define each of the harmonic functions in the electrical network.

HARMONICS ORDER

The fundamental frequency value in Spain is 50 Hz, and the order number defines the number of times in which the harmonics’ frequency is higher than the fundamental value: 1, 2, 3, 4, 5, 6, 7… the natural order of numbers.

It can also be defined as the ratio of the harmonic frequency (fn) and the fundamental frequency (f50)

PARÁMETROS DE LOS ARMÓNICOS Los armónicos se clasifican por tres parámetros (Orden, Frecuencia y Secuencia) que definen perfectamente la función del armónico correspondiente en las redes eléctricas. EL ORDEN DE LOS ARMÓNICOS Partiendo de que la frecuencia fundamental en España es de 50 Hz, el número de orden determina el número de veces que la frecuencia de ese armónico es mayor que la fundamental: 1, 2, 3, 4, 5, 6,7… orden natural de los números También se define como la relación que hay entre la frecuencia del armónico (fn) y la frecuencia fundamental (f50). LA FRECUENCIA Se define como el resultado de multiplicar el número de orden del armónico por la frecuencia fundamental (50 Hz), por ejemplo:

3ª armónica 3 x 50 Hz = 150 Hz 5ª armónica 5 x 50 Hz = 250 Hz 7ª armónica 7 x 50 Hz = 350 Hz

Los armónicos de orden impar son los que se encuentran en las redes eléctricas de la industria, edificios y explotaciones industriales, aeropuertos, etc. Los de orden par sólo aparecen cuando hay asimetría en la señal eléctrica.

LA SECUENCIA La secuencia positiva o negativa de los armónicos no determinan un comportamiento concreto de los mismos en la redes eléctricas, son igual de perjudiciales unos que otros. En el caso concreto de las baterías de condensadores para la corrección del factor de potencia son más perjudiciales los de secuencia negativa, y fundamentalmente el 5º. Por el contrario, los de secuencia cero, al ser su frecuencia múltiplo eléctrico de la fundamental, se desplazan por el neutro, haciendo que por él circule la misma o más intensidad que por las fases con el consiguiente calentamiento del mismo, de ahí la necesidad de igualar la sección del neutro a las fases.

Orden Frecuencia Secuencia 1 50 + 2 100 - 3 150 0 4 200 + 5 250 - 6 300 0 7 350 + 8 400 - 9 450 0 ··· ··· ··· n 50·n ···

FREQUENCy

The harmonics’ frequency is defined as the result of multiplying the order number of the harmonic and the fundamental frequency (50 Hz), e.g:

3rd harmonic 3 x 50Hz = 150Hz 5th harmonic 5 x 50Hz = 250Hz 7th harmonic 7 x 50Hz = 350Hz

Odd-order harmonics can be found in the electrical network of all kind of industries, buildings, indus-trial runnings, airports, etc. Even-order harmonics can be found in unbalanced electric signals.

Sequence+-0+-0+-0...

SEQUENCE

The positive or negative sequence of the harmonics does not establish a specific behaviour of the afo-resaid harmonics in electric networks. They are both equally harmful.

In the particular case of the capacitors’ banks for the correction of the power factor, the most harmful harmonic is that of negative sequence, specially the 5º one.

Instead, harmonics with null sequence have a frequency which is an electrical multiple of the fundamen-tal frequency. These harmonics are displaced along the uncharged wire, so that the current flow is of the same value or even higher than the current flow through the phases. This produces the uncharged wire heating, so it makes it necessary to have the same section on both uncharged and phase wires.

The most usual harmonics parameters are the following:

The total rate referred to the current, THDI, is generated by the non-linear loads in the wiring circuit.

The total rate referred to the voltage, THDU, is the result of a very distorted current in the circuit.

When decomposing a signal into its harmonics in the frequency domain, the harmonic spectrum is formed. This harmonic spectrum can be repre-sented in a bar-graph, by including the percenta-ge of each of the different harmonic signals. The sum of these percentages gives the total analy-sed signal.

In the attached figure a harmonic spectrum, where de 5th harmonic achieves approximately a 25% of the voltage value, can be observed.

ICSThe 3rd and 5th harmonics

THE 3rd HARMONIC

In the figure attached, the distorted wave is repre-sented and its peak value is the graphical addition of both of the sine waves.

The amplitude of the fundamental wave is three ti-mes the 3rd harmonic, and both of them have the peak value in the same instant of time.

The 3rd harmonic has a special feature: its frequen-cy is an electrical multiple of the fundamental fre-quency, and has a null sequence, so that in a three-phase 4wire system (R, S, T and N) there is a mesh entering with the three phases (R, S and T) while there is a shift along the discharged wire (N). This occurs the same way with the harmonics 6, 9, etc.

THE 5th HARMONIC

In the figure attached, the 5th harmonic is repre-sented, as well as the distorted wave with its peak value. This peak value is the graphical addition of the fundamental and the harmonic waves.

As it was previously mentioned, the amplitude of the fundamental wave is five times the 5th harmonic, and both of them have the peak value in the same instant of time.

In contrast to the 3rd harmonic, the 5th harmonic is NOT an electrical multiple of the fundamental wave, so the frequency shift will be through the phases R, S, and T and it will be the 1st harmonic the one who affects the capacitors and the three-phase system, as well as the harmonics 7, 11, etc.

In RTR ENERGIA S.L., these two harmonic distortions (3rd and 5th) are the most important ones when determining the power factor correction in industrial facilities, since the capacitors must be installed forming passive filters (L-C) as it is explained in section D.

BANKS OF CAPACITORS

If there is a possibility of harmonic distortion presence in the electrical network of the facility, an analysis of the electrical network must be made with a properly calibrated network analyser.

RTR Energía S.L. performs this sort of network analyses with properly calibrated equipment when their clients ask for it.

Once completed these network analyses, which must last for approximately 4 or 5 days including a weekend, the necessary data will be obtained in order to diagnose the electrical requirements of the mounting.

• Supply voltage “Uca” • Electric current “Ica” • Frequency • Power in the installation • Power factor • Capacitive energy demanded by the installation • Current in the discharged wire • Unbalance in the mounting because of consumption • THDU since the 3th, 5th, 7th… harmonic (total and for each of the harmonics) • THDI since the 3th, 5th, 7th… harmonic (total and for each of the harmonics) • The predominant harmonic in the network both in voltage and current.

Sometimes, in order to check the harmonics presence in the mounting, performing an analysis for a brief period of time is enough to decide the best capacitors’ bank for the installation.

Following there are some examples shown:

Harmonic distortions spectrum in voltage (THDU) and current (THDI) are obtained by a network analyser. It can be observed, as the distortions are very high, and as it will be seen afterwards, the chosen solution for the set up of the bank of capacitors due to compensate de reactive energy was the placing of passive filtering with an overvoltage of 14%.

In such case, it can be clearly noticed the presence of harmonic distortion, although the net-work analysis will be fulfilled in a brief period of time. It is not this way in the following example.

Both of the impedances depend on the frequency (f), but XL has a direct proportionality with the frequen-cy, while XC is inversely proportional to the frequency. So, when there is a raise in the frequency, the value of the impedance XC decreases while XL increases.

Generally, capacitors in industrial facilities are set in parallel as it can be seen in the equivalent circuit attached.

When this configuration acts as a current divider and the value of XC is the lowest one, the majority of the current will flow through the capacitors, and this is why the capacitors may malfunction.

PARALLEL RESONANCE

Resonance is produced in a parallel circuit when the resultant current and the line voltage are in-phase. When with a specific value of resonance frequency in the parallel L-C circuit, as wR=150 Hz (frequency on the 5th harmonic), this circuit is inductive (w<wR) the current is delayed so voltage will lead current. If the circuit is capacitive (w>wR), current will lead voltage.

In an L-C circuit, the resultant current of the windings (L, etc.) is the same value as the current of the capacitors (C, etc.) but with the opposite sign, so both the algebraic and vector addition have as a result the maximum value of the impedance and a null value of the resultant current (the opposite results of a series circuit).

In this situation, the current in both L-C branches is extremely high which is hazardous for the capacitor as the XC value is the lowest of the whole circuit.

It can be clearly seen in the chart how the impedance (Z) raises until reaching the maximum value.

Because of this, it is necessary to protect the capacitors when they are parallel installed in a high har-monic content circuit.

When an industrial facility, with a high harmonic content, is supplied by a power transformer (medium/ low) it is necessary to have the compensating capacitors installed on the base of the transformer so that they can be protected from the harmonics action (see section G on the reactive energy compensation’s chapter).

CAPACITOR PROTECTION

In presence of harmonic distortions, a passive filter (LC) must be used, as their main function is to pro-tect the capacitors. This filtering is recommended in the standard UNEEN-61642 and as a practical data RTR Energía S.L. establishes that in facilities with distortions on voltage on the 5th harmonic higher than 3%, the installation of L-C filters is required, as well as in 5th harmonic current distortions higher than 30%.

RTR Energía S.L. manufactures two classes of capacitors: Standard which can bear harmonic distortions on voltage lower than 2% and in current lower than 25% and Reinforced which can bear distortions on voltage lower than 3% and in current lower than 30%.

The aim of the repulsion filters is that of avoiding the gain of the facility preponderant harmonic, mainly the 5th harmonic either on voltage or on current and also impeding the parallel resonance between the inductive loads “L” (transformers, starter motors, etc.) and the capacitors “C”, avoiding the overloads and possible damage or destruction of the automatic controlled battery of the bank of capacitors of reactive equalization.

The filter is a cascade arrangement, properly calculated and previously tuned, and is made up of:

• A three phase / single phase reactance. • A three phase / single phase capacitor, with the needed setup power (in kVAr).

This is known as compensation branch, and each of the branches must be designed with the required protection. The various L-C branches form an automatic controlled bank of capacitors,

FILTROS PASIVOS DE RECHAZO El objetivo de los filtros de rechazo es evitar la amplificación del armónico preponderante

múltiplo entero de la frecuencia de la red (50–

which acts as a complete filter with the aim of compensating the power factor of the setup and its ove-rall power is the sum of the power of all of the branches.

HOW TO SELECT A BANK OF CAPACITORS (L-C)

With the network analysis of the facilities’ harmo-nics, the preponderant harmonic can be determi-ned, usually being the 5th harmonic (with a fre-quency value of 250Hz).

Once known the frequency value of the harmonic, the resonance frequency of the filter (wR) is esta-blished and it must never coincide with any inte-ger multiple of the current frequency (50-60 Hz). Among this, the value of the resonance frequency (wR) must be a lower value than that of the prepon-derant harmonic one, so that the resonance with any other harmonic is impossible.

The resonance frequency (wR) is determined through the overvoltage factor (p%), which relates both the capacitor and reactance voltages.

1. General information for MV capacitors

1.1 Total film dielectric

RTR Capacitors have a dielectric constituted in general by three polypropylene films “hazy”, rough in both faces, of high purity. This construction, instead of which it uses only two layers of a rough film in a single one of his faces, common in other manufacturers, confers to RTR Capacitors greater secu-rity of operation and greater life utility. The rough of both faces of polypropylene is a condition indispensable for the complete impregnating of the film during the process and, therefore, for the stability of the capacitor in the long term.

1.2 Impregnating biodegradable

RTR Capacitors use exclusive impregnating the nonchlorina-ted MDBT, developed for the most demanding applications by Elf-Atochem(France). This it is characterized by his high flash point, great capacity of gas absorption derived from the internal electrical unloadings, and total environmental compatibility (biodegradable).

1.3 Construction with folio extended and wild fold

RTR Capacitors is constituted by elementary units, each one of them consisting of aluminum folio windings of high purity and polypropylene films. The aluminum laminae excel towards the ends of the coil, and their edges are folded forming a ring anticrown that confers to the condenser a tension of insepción ofpartial unloadings superior to 50% of the nominal value. The laminae are welded to each other and with the next coils by means of special alloys of great adhesion and low point of fusion. This way the use of “abatis”, characteristic of the previous designs is avoided.

1.4 Under stress

RTR Energía S.L. uses conservative criteria of design that imply the application of dielectric efforts (kV/ mm) relatively low on the materials. Like consequence, the capacitors are of dimensions somewhat greater than those of other marks, with an expec-tation of greater life utility.

1.5 Inner fuses

RTR Energía S.L. incorporates to a great part of their range of MV. capacitors (specially for the greater powers) with the option of individual inner fuses by coil, of new design. Such they allow to isolate the possible failure of anyone of the elements of the capacitor and other elements can still work in normal condition. The fuses are separated to each other, so that it is impossible that the performance of one of them causes the catuación of the fuse next to. In addition, the condensers with internal fuses allow simpler, light and economic constructions.

1.6 Dielectric low losses

The characteristics of their design, the rigorous selection of the manufacture materials and the artisan care put in their construc-tion and process give like result capacitors of low losses, which is translated in smaller this form and operating temperatures, a greater life utility.

Constructive Characteristics Three phase harmonic filters are made of low losses mag-netic plates, permanent regime class F (155ºC) copper con-ductor and 90ºC thermal protection relay.

With the purpose of increasing filters ventilation, windings are separated among them, improving thermal dissipation.

Standard surge factor is 7% and 14% with resonance fre-quency 189 Hz and 134 Hz for 50 Hz networks.

With this standard values in three phase networks and ba-lanced loads, the 5th (250 Hz) harmonic and higher resp-nant phenomenons are eliminated avoiding resonance bet-ween inductive impedance and three phase capacitors for power factor correction and preventing network capacitors and capacitor banks for overloads.
