6 Functions Sepam series 0 Protection functions DE53229 t > >> Earth-fault protection (NSI 50N-5N) Earth-fault protection detects overcurrents caused y phase-to-earth faults. It uses measurements of the fundamental component of the earth-fault current. 2 independent set points (> and >>) the low set point (>) offers definite time (DT) or IDMT settings with various types of standardized curves (IEC, IEEE, RI) and it is possile to enale an IDMT timer hold. the high set point (>>) offers only the definite time (DT) setting. The minimum setting results in instantaneous operation (NSI 50). Depending on the required level of sensitivity, there are three types of Sepam relays. Sensitivity Sensor Setting range Standard 3 phase CTs or earth-fault protection CT, with rated primary current Ino Ino Sensitive () 3 phase CTs or earth-fault protection CT, with rated primary current Ino Ino High sensitivity Special core alance CSH or GO, with ratio of 470/ primary, i.e Ino () Setting not availale with Sepam series 0N. Phase-overcurrent protection (NSI 50-5) Phase-overcurrent protection detects overcurrents caused y phase-to-phase faults. It uses the measurements of the fundamental component of currents drawn from two or three phase CTs, with a secondary rating of or 5. 2 independent set points (I> and I>>) the low set point (I>) offers definite time (DT) or IDMT settings with various types of standardized curves (IEC, IEEE, RI) and it is possile to enale an IDMT timer hold. the high set point (I>>) offers only the definite time (DT) setting. The minimum setting results in instantaneous operation (NSI 50). DE53228 t Thermal image overload protection (NSI 49 RMS) This protection function is used to protect cales and HV/LV transformers against overloads, ased on measurement of the current drawn. The function is ased on a thermal model witch calculates the temperature rise from current measurements. The current measured is an RMS 3-phase current which takes into account harmonics up to numer 3. Two protection settings the continuous maximum permissile current setting which corresponds to the maximum thermal withstand of the protected devices (the continuous permissile current corresponds to a temperature rise of 00 %). the setting for the equipment heating and cooling time constant.

7 Functions Sepam series 0 Protection and measurement functions DE53468 T = 00 ms T > 00 ms Logic discrimination ensures tripping within 00 ms for a fault affecting the sustation usars, while maintaining discrimination with the feeders. Phase-overcurrent and earth-fault protection cold load pick-up The desensitization function avoids nuisance tripping during energizing operations, particularly following a long outage. It temporarily raises the protection set point. High currents during energization may e due to: simultaneous energizing of all loads in an installation (air conditioning, heating, etc.) magnetizing currents in power transformers (these currents can saturate the phase-current sensors and create a false residual current on the secondary of the sensors) motor starting currents. Protection function Phase-overcurrent protection Earth-fault protection () Setting not availale with Sepam series 0 N. Mode of action fter circuit-reaker closing, the tripping set points (I> or I>>) are increased or disaled for the set time. fter circuit-reaker closing, the tripping set points (> or >>) are increased or disaled for the set time. Or This protection is restrained y sensor saturation detection (H2 measurement) () Logic discrimination (NSI 68) This function provides: perfect tripping discrimination with phase-to-phase and phase-to-earth shortcircuits, on all types of network faster tripping of the reakers closest to the source. ll Sepam series 0 relays (N, and ) can send a locking signal when a fault is detected y the phase-overcurrent and earth-fault protection functions. Only the Sepam series 0 relays can receive locking signals which inhiit protection tripping. saving mechanism (exclusive Sepam function) ensures ack-up protection in the event of a locking link failure. External tripping Sepam series 0 can receive, via a logic input, a tripping order from an external protection device. Earth-fault current This function displays the value of the fundamental of the earth-fault current. For this measurement and for earth-fault protection (NSI 50N/5N), the zerosequence input must e connected either to the common point of the three phase CTs or to one earth-fault protection CT or to a CSH20, CSH200 or GO0 core alance CT. Phase currents This function displays the rms phase-current values and takes into account harmonics up to order 3. On Sepam series 0 4, this function displays the three phase currents. On Sepam series 0 3, only the and C phases are connected and displayed. Peak demand currents This function displays the greatest average current on each of the three phases and indicates the current asored y peak loads. 9
