Combined with the communication option, it can provide remote control, annunciation and metering. Sepam 000 S compact. dvantages c indication of phase and earth fault values at the time of breaking provides the operator with useful assistance in determining the causes and seriousness of faults, c the high level of electromagnetic compatibility (EMC) makes it possible to use advanced digital technology-based functions in electrical substations, without the need for any particular precautions, c Sepam 000'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 easy maintenance, c The optional communication function may be used for remote setting, remote metering, remote indication and remote control by means of a two-wire link with a remote control and monitoring system for centralized operation, c setting and testing are extremely simple: v the settings may be made on the front panel (serial link): - one by one, using the TSM00 pocket terminal, or the SFT0 PC software program, - all at once using the SFT PC software program (downloading), v direct readout of primary current and voltage and simple testing of the metering function by injection guarantee the coherency of all settings. 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 000 S (compact), c cabling is limited to: v standard or current transformers or linear CSP type sensors (Rogowski coil principle), v voltage transformers (SX version), v actuators (trip and closing coils). Customization () Standard control and monitoring carried out in Sepam 000's internal PLC can be customized. Sepam 000 SX does not allow for extension of the logic inputs and outputs. For applications which require more logic inputs/outputs, use Sepam 000 type S0 or S0. () Please refer to document Sepam 000 customized application. Sepam 000 SX

4 Metering Sepam 000 is an accurate metering device. It gives a direct readout of values, together with the related units,, V, W... ll the values needed for operation and used for commissioning are available locally and in the control room. Measurements needed for operation Currents Measurement of the current for each of the phases of the circuit. Peak demand currents Measurement of the greatest average current value on the phases. The average current measurement is computed periodically (adjustable period:, 0,, 0 or 0 minutes). The clear button is pressed for zero reset.

7 Control and monitoring () Open / close control Used to control breaking devices equipped with different types of opening and closing coils: c circuit breaker with shunt-trip or undervoltage release coil, c latching contactor with shunt-trip coil, Parameter setting via the TSM 00 pocket terminal, or PC softwares (SFT 0 or SFT ), allows the logic to be adapted to suit the equipment being used (by default, the logic is adapted for control of a circuit breaker with a shunt-trip coil). Lockout relay (NSI ) Stores tripping orders (lockout) and requires user action to be put back into operation (reset). Inhibit closing (NSI 9) Inhibits the closing of the circuit breaker or the contactor according to operating conditions. nnunciation (NSI 0) Keeps the user informed by the display of messages. Logic discrimination (NSI ) Enables quick, selective tripping of the phase overcurrent and earth fault protection relays, whether definite time (DT) or IDMT (standard inverse SIT, very inverse VIT, extremely inverse EIT or ultra inverse UIT). The function triggers the transmission of a "blocking input" signal whenever one of the protection settings is exceeded. Blocking input signal transmission can be used by the Sepam 000 Logic discrimination function for substation, alternator, transformer and busbar connection applications. Trip circuit supervision and discrepancy (NSI ) Detects tripping (by shunt-trip coil) circuit faults. Can be used when the Sepam 000 and the tripping auxiliary power sources have the same voltage rating. If the equipment contains an undervoltage release coil only, the tripping circuit is not supervised since it is fail-safe. This function can also detect position information discrepancies (neither open nor closed or simultaneously open and closed) in the different control schemes. The connection of inputs I, I and trip output O on the ESB board must be done according to other connection schemes. Detection of plugged connectors (NSI ) Indication on the display unit that one or more connectors are not plugged in (the detector itself must be connected: see connection schemes). Operation counter () Counts the number of closing operations made by the breaking device, thereby facilitating equipment maintenance. Phase fault trip counter () Counts the number of operations for which breaking performances were required, thereby facilitating equipment maintenance. Disturbance recording triggering Triggers recording of electrical signals and logical states by: c voluntary local or remote action, c instantaneous overcurrent and earth fault protections, c protection tripping order. () according to parameter setting. () counter reading is via serial link on the front panel of Sepam 000, and via Jbus/Modbus communication. Sepam 000 SX
