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 Sepam’s 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 2000’s 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. Sepam’s robustness and its outstanding electromagnetic compatibility(EMC) allow it to be used in highly disturbed environments without requiring anyparticular precautions.

Sepam 2000
Standard Sepam 2000 is delivered with its connectors.
PresentationSepam 2000 is focused on performance.It can be used for the most demanding applications.
Sepam 2000 has a large control and monitoring capacity, provided by its built-inPLC and interface for communication with a centralized control system.The built-in PLC considerably cuts down on the use of auxiliary relays and theassociated wiring.
Each Sepam 2000 is supplied with its standard control and annunciation program,which allows it to be used without any additional engineering work or programming.The available data as well as Sepam 2000’s remote control capacity enable it to beintegrated in an energy management system. Sepam 2000 reports to the controlroom, so the user is immediately informed of any situation. Having this informationat his disposal, he can take the appropriate measures without leaving the controlroom.
Each Sepam 2000 is designed to meet all the application needs and includesall the necessary functions, ready for use.Simply choose the appropriate Sepam 2000 from the selection tables showingthe functions available for each application (1) :c substations,c busbars,c transformers,c motors,c capacitors,c generators.
Example :An incomer in a substation with multiple supply sources, in a high impedanceearthed system, should be equipped with:c definite time or IDMT phase overcurrent and earth fault protection,c directional overcurrent and, sometimes, directional earth fault protectionfor discrimination between parallel incomers.c an undervoltage relay to control supply source changeover.c all the measurements and accumulated energy readings needed to operatethe substation. For this application, the S03 type Sepam 2000 could be chosen,including the standard control and monitoring functions, such as trip circuitsupervision and logic discrimination.

Simple setting with the TSM 2001 pocket terminal.
DescriptionSepam 2000 replaces measuring instruments suchas ammeters, voltmeters, wattmeters,energy meters, etc.It displays alarm and operating messages related tothe protection functions and control logic systems,thereby eliminating the many indicating lamps foundon previous installations.The front face includes:c a lighted alphanumerical display, legible from adistance of several meters,c keys to select the measurement to be displayedand to acknowledge messages. As a security feature,these keys do not give access to the protectionsettings,c 3 lights:v “trip” (tripping by the protective relay),v “circuit breaker open”,v “circuit breaker closed”,c a green light indicating the presenceof “auxiliary power supply”,c a red light signalling malfunctions and relay fail-safeposition (watchdog),c a door for access to:v to the serial connection inlet,v the cartridge slot.The cartridge contains the different programs requiredfor Sepam 2000 operation.
Installation and connectionSepam 2000 is delivered with its connectors.The connectors are individually disconnectablescrew-on terminals.All types of Sepam can be installed by makinga simple rectangular cut-out in the mounting support.Some types of Sepam 2000 also come in a compactversion (S26).
Control logic and annunciationEach type of Sepam 2000 is equiped with a built-in PLC with at least 10 logicinputs and 6 logic outputs (which can be extended to 26 inputs and 14 outputs).This flexibility is provided for standard network management automation functionssuch as logic discrimination, reclosing, load shedding, etc.Customized process control programs may also be developed on Sepam(see “for customized applications” document).
OperationSepam 2000 is simple to consult and set thanks to the serial link on the front of thedevice.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),The TSM 2001 pocket terminal is equiped with a keyboard, a 4-line display(20-character per line) and a menu system.It is easy to read measurements, enter settings, modify operating conditionsand review maintenance information such as “fault current”, “number of c.b.operations”, etc.Access to the protection function settings is protected by a password.Sepam 2000 stores the parameters and the settings in its non volatile memory.In the event of an auxiliary power supply failure, they are saved and retrievedas soon as the power is restored.
