Sepam concept

Electromagnetic compatibility testing is performedin an anechoic chamber.

Kirchhoff protection testing laboratory.

Mastery of digital techniquesAs a result of the success of the first Sepam unit, Merlin Gerin developeda new range: Sepam 1000+ and Sepam 2000.This range is more comprehensive,more effective and fully appropriate for the control of electrical substations in publicand industrial distribution systems. All protection and control devices must:c supply optimal service under the best security and availability conditions,c ensure dependable operation in the highly disturbed electrical substationenvironment.To achieve these objectives, the development of this new range calledfor substantial implementation of expertise and enhanced investigationsin the following main areas:c electrical phenomena, transient operation,c signal processing,c protection algorithms,c electromagnetic compatibility (EMC),c dependability, reliability,c communication networks.During the design phase, dependability studies (FMECA (1)) were carried outto determine the hardware and software architectures, considerably improvingavailability and operating security.All the studies were performed in accordance with a stringent quality plan.A large number of qualification tests were performed, in a dedicated protectiontesting laboratory (Kirchhoff laboratory).The protection functions are tested in the laboratory by simulating the phenomena(EMTP (2)) as they appear in electrical networks.

Major advantagesThe use of digital techniques provides protection and control devices with majoradvantages:

AvailabilityThe use of extensive self-testing and self-diagnosis procedures allows wide-rangemonitoring of the device.The user is continuously informed of Sepams operating condition.He can therefore take immediate and efficient action in the event of a failure.The risk of running an installation with faulty protection is substantially lowered.Periodic testing is no longer essential.

Global cost reductionThe integration in a Sepam of all the functions needed for the protection andcontrol of a system offers substantial advantages such as more rational operation,optimized performance and better service for a reduced overall cost.Reduction in the cost of:c design: by the choice of units that are ready to use, without requiring detailedengineering work,c installation: by the integration of auxiliary relays, measuring instrumentsand annunciation devices,c commissioning: by simple installation and testing,c operation: by remote control and improved access to more complete information,c maintenance: by the reduction of preventive maintenance.

DependabilityExtensive dependability and reliability calculations have been carried outon Sepam. They show that the failure rate, and therefore the risk of misoperation,is minimized with an integrated Sepam type solution.

SimplicitySepam requires only simple parameter setting (calibration of the currentand voltage transformers, and general information on the network).FlexibilityThe flexibility of Sepam 2000s built-in PLC makes it suitable for all possiblecontrol logic schemes.

3Sepam range

A complete rangeAll applicationsThe Sepam range is a set of protection and control units which have the capacityto fullfil all types of applications:c substations,c busbars,c transformers,c motors,c capacitors,c generators,c measure and control.Each Sepam is an optimized solution in terms of functions, performance and price.

All functionsEach Sepam includes all the protection, metering, control, monitoringand annunciation functions required for its assigned application.The functions have very wide setting ranges, all types of curves, and can thereforefit into any protection system.The choice of functions offered in each Sepam is the result of the engineering,experience and expertise of Merlin Gerin specialists who are confronted daily withthe challenge of developing electrical equipment projects.In addition, the so-called logic discrimination function makes it possible tofurther lower the tripping time when a fault occurs, whatever the time discriminationintervals and the type of curve (definite time or IDMT).This principle makes it possible to incorporate economical busbar protection,or to set a shorter protection time delay upstream than downstream,and still maintain tripping discrimination.It means that Sepam can meet the protection and control needs of low voltagenetworks and high voltage networks up to 220 kV as efficiently as required.

Industrial rangeThe design of all the types of Sepam for each application is basedon two hardware units: Sepam 1000+ series and Sepam 2000 series.The hardware manufacturing process is ISO9001 certified and includes a burn-incycle. Sepams robust and its outstanding electromagnetic compatibility (EMC) allowit to be used in highly disturbed environments without requiring any particularprecautions.

Installation of CSH core balance CTs.

Standard current sensorsSepam is adapted for all types of phase and residual current sensors:standard 1A or 5A with rated currents from 10A to 6.25 kA.

CSP current sensorsThe CSP type current sensors, designed by Merlin Gerin, operate accordingto the Rogowski coil principle. The CSP sensors incorporate a special coilingtechnique and have no magnetic core. This provides them with the followingproperties:c no saturation: linear response,c no hysterisis or remanence: transient phenomena are accurately reproduced,without any wave form deformation.CSP type current sensors are used with Sepam 2000.The CSP-Sepam 2000 assembly forms a coherent protection and metering chain,which results in the following advantages: simplification of current sensorspecifications,(choice among only 4 sensors),

Presentation

Contents

Motor protection and control consists of performingthe metering, protection, control and monitoringfunctions required for operation.Sepam 2000 provides all these functions globally.All the equipment and mechanisms that are generallyfound in a MV cubicle control cabinet are replacedby a single device which performs:c protection,c metering,c control and monitoring using protection functionsand logic inputs to activate the trip outputs, closingoutputs, etc. and annunciation.

Advantagesc Indication of phase and earth fault current values at the time of breaking providesthe operator with useful assistance in determining the causes and seriousnessof the fault,c The high level of electromagnetic compatibility (EMC) makes it possible to useadvanced digital technology functions in electrical substations, without the needfor any particular precautions,c Sepam 2000's continuous self-testing sets the device in a predetermined fail-safe position whenever a failure occurs, thereby preventing random operation,c Terminals that are individually disconnectable while energized allow easymaintenance, The optional communication function can be used for remote setting, remotemetering, remote annunciation and remote control via a 2 wire link with a remotecontrol and monotoring system for centralised operations.c Setting and testing are extremely simple:v the settings may be made on the front panel (serial link):- one by one, using the TSM2001 pocket terminal, or the SFT2801 PC softwareprogram,- all at once using the SFT2821 PC software program (downloading),v a direct readout is given for primary current and voltage and for the meteringfunction, simple testing by injection guarantees the coherency of all settings.c Each Sepam 2000 is designed to meet all the application needs and includes allthe necessary functions ready for use (protection functions, metering, control logicand communication).The control logic may be adapted to most usuals schemes by a simpleparametring. This allows a better safety and optimization of wiring.

The wide setting ranges provide for the most widely varied cases.Installation in the switchboard is simplified:c just one device to install, the Sepam 2000. It comes in two modelswith different widths:v standard S36,v compact S26 (for certain types).c cabling is limited to:v standard 1A or 5A current transformers or linear CSP sensors (Rogowski coilprinciple),v voltage transformers,v temperature probes (RTDs),v control and annunciation units (start/stop pushbutton, device position, etc),v actuators (trip and closing coils).

Customization (1)Standard control and monitoring carried out in Sepam 2000's internal PLC can becustomized. The number of inputs and outputs can be increased by addingextension boards (please contact us for further information).

Protection

Thermal overload (ANSI 49) F431*Protection of equipment against thermal damagecaused by overloads. Thermal overload is calculatedaccording to a mathematical model, with 2 timeconstants (T1 and T2), taking into account the effectof negative sequence current by meansof an adjustable weighting coefficient.The function comprises:c an adjustable alarm setting,c an adjustable trip setting.Phase overcurrent (ANSI 50/51) F011, F012*Three-phase equipment protection againstphase-to-phase (short-circuit) faults.The following types of time delay settings areavailable: definite, standard inverse, very inverse,extremely inverse or ultra inverse.Recommendations:c set higher than starting current,c instantaneous operation if the equipmentis controlled by a circuit breaker or contactor only.c time delayed operation if the equipmentis controlled by a contactor-fuse combination so thatthe fuse blows before the contactor when the faultcurrent is greater than the contactor's breakingcapacity.

Earth fault (ANSI 50N/51N or 50G/51G) F081, F082*Connection and equipment earth fault protection.The following types of time delay settings are available:definite, standard inverse, very inverse, extremelyinverse or ultra inverse.When earth fault current is detected by taking thesum of the 3 phase CTs, a harmonic 2 restraint isused to do away with transformer closing relatedtripping.Recommendations:c connection to special-purpose CSH core balanceCT for greater sensitivity,c definite time operation.

Negative sequence / unbalance (ANSI 46) F451*Protection of equipment against overheating causedby an unbalanced power supply, phase inversion orphase break, and against low levels of overcurrentbetween 2 phases.Recommendation:c use IDMT curves.

Locked rotor / excessive starting time(ANSI 48/51LR) F441*Protection of motors that are liable to startwith overloads or insufficient supply voltageand/or that drive loads that are liable to becomelocked (e.g. crusher).Locked rotor protection function is only confirmedafter a time delay that corresponds to the normalstarting time.

Phase undercurrent (ANSI 37) F221*Pump protection against the consequences of primingloss. This protection detects delayed undercurrentcorresponding to motor no-load operation whichis typical of a loss of pump priming.

Starts per hour (ANSI 66) F421*Protection against overheating caused by too frequent starts.Checking of:c the number of starts per hour,c the number of consecutive warm starts (detected by the thermaloverload protection),c the number of consecutive cold starts.The protection inhibits motor energizing for a preset time period when thepermissible limits are reached.

Positive sequence undervoltage (ANSI 27D) F381, F382*Protection which prevents motor malfunctioning due to insufficient or unbalancedsupply voltage.

Direction of rotation (ANSI 47) F381*Protection which prevents the changing of direction of motor rotation followinga power supply modification.

Directional earth fault (ANSI 67N) F501*Highly sensitive earth fault protection for motor feeders supplied by long cablescharacterized by high capacitive current.

Reverse real power (ANSI 32P)Protection of a synchronous motor against operation as a generator when drivenby its load.It is based on the "real overpower" F531* function.

Reactive overpower (ANSI 32Q/40) F541*Protection of a synchronous motor against field loss which causesoverconsumption of reactive power and leads to the loss of synchronism.

Temperature monitoring (RTDs) (ANSI 38/49T) F461...F466, F471...F476*Protection which detects abnormal overheating of motors (bearings and/orwindings) equipped with Pt 100 type platinum resistive temperature devices:c 1 alarm setting,c 1 tripping setting.The RTD cabling is continuously monitored.

Motor differential (ANSI 87M) F621*Fast, sensitive motor protection against internal faults due to damaged insulation.The protection is based on the principle of percentage differentials. It includesstarting current restraint to sustain stability in spite of its high level of sensitivity.

Current sensor sizingc The current sensors should be sized so as not to be saturated by the currentvalues which they are required to measure with accuracy (at least 5 In):c For differential protection:the current transformers should be of the 5P20 type.The power rating must be chosen so that the wiring resistance (R

w) is less than the

rated load of the current transformer (VACT), i.e.:VACT > Rw . In2

In: CT rated current at the secondary of the CT.

Control and monitoring

Open / close controlUsed to control breaking devices equipedwith different types of opening and closing coils:c circuit breaker with shunt-trip or undervoltagerelease coil,c latching contactor with shunt-trip coil,c contactor with impulse or latched order control.

Parameter setting via the TSM 2001 pocket terminal,or PC softwares (SFT 2801 or SFT 2821), allows thelogic to be adapted to suit the equipment being used(by default, the logic is adapted for control of a circuitbreaker with a shunt-trip coil).

The opening order (via input I13) differs accordingto the programmed type of control:c normally open contact for shunt trip coil (circuitbreaker or contactor with latched order control),c normally closed contact for undervoltage releasecoil (circuit breaker or contactor with impulseor permanent order control).Lockout relay (ANSI 86)Stores tripping orders (lockout) and requires useraction to be put back into operation (reset).Inhibit closing (ANSI 69)Inhibits the closing of the circuit breaker or thecontactor according to operating conditions.

Annunciation (ANSI 30)Keeps the user informed by the display of messages.

Load sheddingCauses a shutdown as a result of an external orderor a drop in network supply voltage(except for M02, M05 and M20).RestartStaggers motor restarts after a brief voltage dropso as to avoid overloading the network.

Logic discrimination (ANSI 68)Enables quick, selective tripping of the phaseovercurrent and earth fault protection relays, whetherdefinite time (DT) or IDMT (standard inverse SIT,very inverse VIT, extremely inverse EIT or ultrainverse UIT).The function triggers the transmission of a "blockinginput" signal whenever one of the protection settingsis exceeded. Blocking input signal transmission canbe used by the Sepam 2000 Logic discriminationfunction for substation, generator, transformer andbusbar connection applications.

Trip circuit supervision and discrepancy (ANSI 74)Detects tripping (by shunt-trip coil) circuit faults.Can be used when the Sepam 2000 and the tripping auxiliary power sources havethe same voltage rating.If the equipment contains an undervoltage release coil only, the tripping circuit isnot supervised since it is fail-safe.This function can also detect position information discrepancies (neither opennor closed or simultaneously open and closed) in the different control schemes.The connection of inputs I1, I2 and trip output O1 on the ESB board must berespected (see other connection schemes).Detection of plugged connectors (ANSI 74)Indication on the display unit that one or more connectors are not pluggedin (the DPC terminals must be connected: see connection schemes).Operation counter (1)Counts the number of closing operations made by the breaking device, therebyfacilitating equipment maintenance.

Running hours counter (1)Determines the time during which the breaking device (contactor or circuit breaker)is in the in service-closed position, i.e. the number of hours of operation(0 to 65535 hours).Phase fault trip counter (1)Counts the number of operations for which breaking performances were required,thereby facilitating equipment maintenance.

Disturbance recording triggeringTriggers recording of electrical signals and logical states by:c voluntary local or remote action,c instantaneous overcurrent, earth fault and motor differential protections,c protection tripping order.

(1) counter reading is via serial link on the front panel of Sepam 2000, and via Jbus/Modbuscommunication.
