Locking can prevent the P-coil from being automatically adjusted grid components have to switched deactivated during lengthy earth fault searches. The switching states four big lines and their capacitive current can taken into account. binary input tells the REG-DP/ REG-DPA whether the line switched OFF. This can suppressed with locking. The below table shows the list options for the regulator's behaviour: ICE Ipos A abs(IF) A ICE + Idetuning a) b) ICE_2 c) Figure 77: Ipos the event earth fault based the selected correction method .Page 107 Detailed description REG-DP/ REG-DPA parameters 0 Locking The above describes how the regulator automatically starts new tuning process the end of the delay time set for earth fault. locking en- abled, the regulator switches MAN mode after the transient earth fault time and must be switched back AUTO mode either manually, through the SCADA system onsite. Default setting: OFF: 0 Ipos correction To further minimize the current across the faulty section, the REG-DP resonance regulator can adjust the P-coil when earth fault occurs
