Non-directional Overcurrent Protection, ground
The dynamic pickup thresholds for the ground currents of the overcurrent protection are set at the following
addresses:
50Nc-1 PICKUP
50Nc-2 PICKUP
50Nc-3 PICKUP
51Nc PICKUP
51Nc-1 PICKUP
The tripping times for the ground currents of the overcurrent protection are set at the following addresses:
50Nc-1 DELAY
50Nc-2 DELAY
50Nc-3 DELAY
51Nc T-DIAL
51Nc T-DIAL
51Nc T-DIAL
51Nc-1 T-DIAL
The characteristics for the ground currents of the overcurrent protection and their possible settings are
entered at addresses:
1911 51c IEC Curve
1912 51c ANSI Curve
1913 51Nc Recloser
1917 51Nc-1 IEC Cu.
