LED 1 is used for overcurrent and LED 4 for negative-sequence overcurrent protection operate indication. LED 4 is also used for phase discontinuity protection operate indication. The upstream blocking from the start of the overcurrent second high stage (PHHPTOC2) is connected to the output SO1 (X110:14-16). This output is used for sending a blocking signal to the relevant overcurrent protection stage of the IED at the infeeding bay.

According to the order code, the directional earth-fault protection method can be based on conventional directional earth-fault (DEFxPDEF) only or alternatively together with admittance criteria (EFPADM) or wattmetric earth-fault protection (WPWDE) or harmonic based earth-fault protection (HAEFPTOC). In addition, there is a dedicated protection stage (INTRPTEF) either for transient-based earth-fault protection or for cable intermittent earth-fault protection in compensated networks. A dedicated non-directional earth-fault protection block (EFHPTOC) is intended for protection against double earth-fault situations in isolated or compensated networks. This protection function uses the calculated residual current originating from the phase currents. 1MRS756378 K Section 3 REF615 standard configurations REF615 99 Application Manual The binary input 2 (X110:3-4) is intended for directional earth-fault protection blocks’ relay characteristic angle (RCA: 0°/-90°) or operation mode (I0Sinφ/ I0Cosφ) change.

It can be used, for example, as a nonselective backup protection for the selective directional earth-fault functionality. The operation signal is connected to alarm LED 3.
