to the resonance point and the current correction.
If, the other hand, switch-offs switches other grids are performed isolate the
earth fault, the current coil position must corrected the absolute value the switch-
off switch.
At the end the transient earth fault time, the P-coil
is adjusted the last calculated resonance point. The determination the

Tuning+Correction Readjust set value
At the end the transient earth fault time, the P-coil
is readjusted set value.
The values dIc_1 dIc_4 enable the coil posi-
tion corrected for lines when earth
fault occurs.
The value for the corresponding binary input
could be, for example, Ear_Corr1 for the feeder
for dIc_1.
