The Third Harmonic - a Growing Problem

Today's electrical networks and plants are under much more stress than a decade ago. One reason for this is the increasing use of electric equipment that generate harmonics: in particular the third harmonic. This harmonic can generate exceptionally high neutral currents which can often exceed even the phase current.

Equipment that generate harmonics: • Fluorescent lighting systems • Computers • Welding equipment • UPS • Rectifiers • TV monitors • Microwave ovens

The Third Harmonic Causes Many Problems

Problems are directly related to the harmonic content. The third harmonic found in the phase current appears neutral thus increasing the neutral current. See illustration above.

In network:

• Overheating • Increased power losses • Poor quality of electricity • Electromagnetic fields • Malfunctions in earth fault control • Failure in remote control systems

In plants:

• Malfunction in electronics • Damage to capacitors • Power losses • Increased magnetic fields • Overload in neutral conductor • Cable fires • Abnormal temperature changes and noise in transformers • Nuisance tripping in circuit-breakers • Shorter life time

The third harmonics are accumulated

in the neutral conductor.

The Solution- The Third Harmonic Filter THFstar

The third harmonic filter THFstar removes the third harmonic current from the network. The third harmonic currents generated by the single phase loads flowing in the phase conductors sum up in the neutral conductor. The neutral current may be higher than the phase current.

The THF filter mitigates the third harmonic current from the whole network from the luminances to the distribution panel, main switchboard up to the supply transformers medium voltage winding. The mitigation effect is the same both at the line and load side. The filtering application is patented.

effects on third harmonic currents.

Benefits of THF for lighting and mixed load

Increased efficiency in low voltage network • Reduction in transmission losses • Increased loadability of the existing network and switchboards • Lower temperature of cables, switchboards and transformers • Elimination of third harmonic current in neutral and phase conductor

Increased efficiency in lighting appliance and pc-load • Less power or more lighting • Less maintenance • Longer lifetime of the lamps and capacitors

Reduced Magnetic fields • The reduction of third harmonic component of the current reduces the total magnetic field • Diagram indicating an example of the total magnetic field spectrum typically in various locations

Third harmonic filters THFstar and THF

The size of the THF-filters is selected according to the supply transformer or back up fuses. The protection unit needs to be used, in case the dimensioning exceeds the thermal rating of the filter.

The basis of dimensioning is that the filter withstands the 150Hz voltage and the fundamental neutral current generated by the phase unbalance.

The THFstar filters are tested according to the highest possible short circuit current or back up fuse.

Third Harmonic FilterSelection and dimensioning

Installation to the transformer star point, enclosed filters and system components,THFstar The new generation third harmonic filter THFstar is designed for small size and economical solutions to places, which are especially exposed by third harmonic currents. The filter can be installed outdoor in vicinity of transformer stations, as retrofitting to existing transformer station or as additional field of main switchboard. It is recommended to install the filter THFstar in PEN-conductor, whenever possible, equipped with appropriate protection unit THF1S_ .

DIMENSIONING: According to the supply transformerPROTECTION: Protection unit THFS1_S, 50Hz and 150 Hz measurement according to the mounting instruction

Installation for distribution boards in TN-S-system, enclosed filter and system components, THF THF filters are designed in TN-S-systems to provide selective mitigation of isolated groups with local or central compensation. The THF is normally installed in the load side neutral output of UPS-devise. THF is dimensioned according to the group fuses. In case the dimensioning is below 100% it is recommended to use additional protection unit. The filter types THF 25...160NV include guard units to keep track of the PE-current in the area of 4...10 A.

Type: THFS 1600 S1Rated voltage: 400VDimensioning according to the transformer size:1600 kVARemoves the third harmonic current from the phase and neutral conductorDimensioning current/ Max continuous current: 2250A/ 800ADimensioning voltage: 40V 150Hz The filter allows subsequent increasing of the harmonic load without retrofittingShort circuit dimensioning according to max. available short circuitThe filter is stand along type and not influencing on the power factor compensationThe filter is not influencing on carrier- wave-line.Main incoming breaker: Max. time delay: 0,2 s Terminations: Max six cables of 300mm2

The filter is equipped with by-pass switch for commisoning

Stand along enclosure: • indoor use IP30 • outdoor use IP34Accommodation: • In the vicinity of transformer station • Retrofitting to the transformer station • In the main switchboard

The THFstar removes typically 95% of the third harmonic current from the whole network from line and load side independent of the magnitude of the third harmonic current. For example the neutral current reduces from 450A down to 25A and in the phase conductors from 150A to 10A. The same mitigation prevails in the whole network from the transformer windings to the lamps and computers.The magnetic field from the construction and earthing wiring reduces typically by 50% due to mitigation of the vagabonding currents ( 50% of magnetic field usually of 150 Hz origin).

The iron, copper and resistance losses reduce the temperature and noise level of the supply transformer doubling the lifetime of the transformer by every 8 degrees C.The filter reduces the resistance losses (I2R) For example:Before: (450A)2 x 0,1 WΩ = 2025 WFilter installed: (25A)2 x 0,1 WΩ = 62,5 WThe filter include protection unit, which limit the 50Hz unbalance current and 150Hz fault curre

Installation and commissioning:The installation of THFstar is in theory easy but in practice certain points have to be checked :

• Ensure by measurement that there is no parallel current path to the filter • Check up also the possible influence of parallel transformers or generators • Ensure that the filter is installed in the right location. The neutral conductor from the star point of the transformer is the recommended place. • Check up that the current measurement is right. The CT shall always measure the sum of all neutral and earth currents of the network. • Check up the relay setting of the protection unit. • Read mounting instruction 34THF1S • Check that there is no largely dimmer loads.

LV Capacitor CLMDDescription

Reliability for Power Factor Correction

CLMD construction • The CLMD capacitor consists of a number

of wound elements made with a dielectric of metallized polypropylene film. These dry windings are provided with a sequential disconnector ensuring that each element can be reliably and selectively disconnected from the circuit at the end of its life.

• The capacitor elements receive a treatment under vacuum in order to ensure perfect electrical characteristics. Each winding is placed in a plastic case and encapsulated in thermo- setting resine in order to obtain a perfectly sealed element.

• The elements are placed inside a sheet steel box and connected in such a way as to supply the single or three- phase power at the required voltage and frequency.

• The sheet steel box is filled with inorganic, inert and fire proof granules in order to absorb the energy produced or to extinguish any flames in case of a possible defect at the end of an element’s life. The CLMD is also provided with thermal equalizers to ensure effective heat dissipation.

High performance in-house metallised film ABB’s completely integrated manufacturing process has resulted in the development of the special ABB high-performance film of which all ABB L. V. capacitors benefit: • high breakdown strength • excellent peak current handling capability • high capacitance stability • optimal self healing design • long life

Reliable and safe

Dry type designThe CLMD has a dry type dielectric and thereforecannot give any risk of leakage or pollution of theenvironment.

Very low lossesDielectric losses are less than 0.2 Watt per kvar.Total losses, including discharge resistors, are lessthan 0.5 Watt per kvar.

Long life - Self- healingIn the event of a fault developing in the dielectricof the capacitor, the metallized electrode adjacentto the fault is immediately vaporized, thus insulatingthe fault. The capacitor then continues normaloperation.

Fire protectionAll capacitor elements within the CLMD capacitorare surrounded by vermiculite which is aninorganic, inert, fire proof and non toxic granularmaterial. In the event of any failure the vermiculiteabsorbs safely the energy produced within thecapacitor box and extinguishes any possible flames.

Unique protection systemA unique Sequential Protection System ensures that each individual element can be disconnected

from the circuit at the end of its life.

Easy to install - Light weightThe CLMD capacitor is very lightweight andtherefore presents no handling difficulties duringinstallation.

High reliabilityThe CLMD capacitor complies with therequirements of IEC 831- 1 & 2. The use of robustterminals removes the risk of damage duringinstallation and reduces maintenance requirements.

SecurityThermal equalizers are fitted to surround eachcapacitor element and provide effective heatdissipation. The CLMD capacitor is equipped withdischarge resistors.

ISO 9001Our ISO 9001 Quality System registration providesthe strongest assurance of our product quality.

ISO 14001The CLMD capacitor has a dry type dielectric andis free from liquids or other impregnating agents.It has been designed for environmentally friendlymanufacturing. Our ISO 14001 certificationguarantees our commitment to the environment.

Arc faultsMost short circuit faults in LV and MV switchgears are accom-panied by an electric arc. An arc fault always leads to consider-able damage to equipment and personnel unless it is distinguis hed very fast. The fault should be disconnected as fast as possible and in less than 0.1 s to avoid serious damages and give involved person a fair chance to survive the accident without severe damages. This is a demand found in the electrical safety rules in all CE countries, ref. IEC364-4-42.

The Arc Guard System TVOC is an aid to quickly detect an arc fault and trip the incoming circuit-breaker. The main advantage with the Arc Guard System is that it can trip instantaneously, i.e. override other tripping functions.

FunctionThe Arc Guard System TVOC is used for high-speed tripping of the main circuit-breaker in the event of an arc fault.

Arc Monitor with detectorsThe unit reacts to short-circuit arcs and immediately transmits a tripping signal.• A maximum of nine detectors can be connected to each Arc Monitor unit. (Max. four detectors for the simplified version).• Normally only one detector is required in each compartment• The Arc Monitor can be located anywhere in the switchgear.• For practical reasons, the length of the optical fibre cables should

be kept to a minimum.Should an arc occur, the detector concerned transmits the light to theArc Monitor and a solid state contact in it operates within a millisecond. This contact is connected in series with the shunt release of the circuit-breaker. Even if the over-current release of the circuit-breaker is delayed to provide selectivity, this does not influence the operation of the Arc Monitor.

Current Sensing UnitIn addition to the light produced by arcs, the Arc Monitor is also sensi-tive to other sources of intense light such as photo flashes, sunlightdirectly on the detector, intense lamp light close to a detector or normal arc light from such large items as circuit-breakers. By combining the Arc Monitor with a Current Sensing Unit, a current logic condition is introduced that prevents circuit-breaker tripping by none relevante light sources.

EMC featureThe switchgear and controlgear equipment in which the Arc Guard System is intended to be placed generally represents a severe environment in terms of electromagnetic interference. High currents in busbars and cables, switching of inductive loads, arcs from switching equipment etc. generate electromagnetic fields of considerable strength.

Electrical wires act as antennas and pick up electrical interference voltage. By using optical fibres the Arc Monitor installation is not sensi-tive to electromagnetic interference.

The basic EMC publications IEC 1000 define different electrical environment classes and corresponding test levels. A switchgear is generally regarded as a more severe electrical environment than a typical industrial electrical installation. The Arc Guard System TVOC is tested acc. to the test level for servere industrial environment or switchgears with mixed signal and power cables.

The Arc Guard System is tested according to following standards:IEC 1000-4-2, level 3IEC 1000-4-3, level 3IEC 1000-4-4, level 4 and corresponding part of SS 436 15 03, PL4IEC 1000-4-5, level 4/3IEC 1000-4-6, level 3IEC 1000-4-11IEC 1000-4-12, level 4/3

The Arc Guard System fulfils the requirements for CE-marking acc. to:The EMC-directive 89/336/EEC, tested according to EN 50081-1 andEN 50082-2. The Low Voltage Directive 73/23/EEC.

The Arc Guard System is UL-listed.

System securityThe Arc Guard System is a product to ensure highest possible safety level and is expected to operate with absolute dependability.The system is provided with testing functions and it should be checkedat regular intervals.

The test procedure is described in the instruction manual.

Current sensing unit• For AC and DC• Terminals for connection of external current transformers.• The function of the current sensing unit is to block the tripping of the arc monitor at a load current below a certain adjustable value.• The unit incorporates a selector switch and a potentiometer for

testing purpose.• Power consumption is approx. 11 W.• Optical signal trans mis sion• If several Current Sensing Units are needed, they can be connected

in series using optical cables.• LEDs indicate when the load current exceeds approx. 70%

and100% of the set value.

Connection of current trans form ersThe unit is to be connected to current transformers with a rated secondary

Out current of 1, 2 or 5 A.Note that current transformers for relay protection are to prefer sincethese do not saturate as quickly as ordinary current transformers. Thetransformers selected should not saturate before at least 2 times the set over c

Detectors and Optical cablesGeneralThe used optical plastic fibre cables are prefabricated and can not be cut or joint and they must be run in smooth curves during the in-stal la tion. Both Detector cables and Optical cables are available in certain standard lengths, see the ordering table. Other lengths can be quoted on request. Maximum length, see ordering table. The plastic fibre is made of polymethylene acrylate (PMMA) with a jacket of PVC.

DetectorsEach detector consists of an optical cable and a lens that are calibrated together to get the same sensitivety independent of cable length. The detector has a plug-in connector that fits to the arc monitor. The lens collects light from all directions, with exception of a small shaded area behind the detector. See polar diagram below.Practical experiments have shown that arc light reflected between me-tallic surfaces may be sufficient to cause tripping.

A maximum of nine detectors can be connected to Arc Monitor 1SFA 663 001 R1001 and 1SFA 663 001 R1002 . To the simplified version 1SFA 663 001 R1003 four detectors can be connected

If more detectors are required, several units can be connected in parallel.

Tripping of several breakersFor tripping of several breakers an intermediate relay is often required. In order not to delay the tripping function a relay of fast acting type (4 ms) is recommended.

For DC trip circuits ABB’s relay of type RXMS (Order Code.RK 216 263-...) is suitable. Where a greater load capacity is required this relay can be connected in parallel with a relay of type RXMH (Order Code RK 223 067-...).

In DC trip circuits it is necessary to add an external break contact inseries to reset the triacs after tripping.

An impulse relay with an indication flag can be used to indicate a tripped Arc Monitor even after loss of auxiliary voltage. A suitable impulse relay of type E251, E252, E254, E255 or E256 can be choosen from our system ProM assortment.

Arc Monitor• Available for AC and DC supply.• The two output stages are triacs triggered via a pulse transformer.

In this way, the output stages are galvanically separated from each other and from other circuits.

• The Arc Monitor has two separate relay outputs. Each relay has one change-over contact function. Relay K1 is used for EXTERNAL

TRIP indication and relay K2 is used for POWER ON indication.• A switch is included for selection of automatic relay resetting (after approx. 200 ms) or manual resetting of relay K1.• A digital display, visible through the window in the door, shows

which detector has caused tripping. The display and relay are reset by the pushbutton in the door. The Arc Monitor can trip again even if it is not reset.

• Terminals for connection of power supply voltage, circuit-breaker trip circuits and signal circuits. Optical plug-in connectors are provided for the detectors and for the communication cables to other units. (Not for the simplified version)

• The power consumption of the unit is approx. 6 W. Energy is stored in the unit for operation up to 0.2 s if the supply voltage would fail, this is sufficient to activate the output even if voltage disappears in conjunction with a short circuit fault.

The current sensing unit can be either 1, 2 or 3-phase connected, however, three-phase is to prefer for safety reasons.

The burden of the unit is only 0,7 VA so current transformers for otherpurposes can often be used.
