The value relates the P-coil's upper end value Imax A.1.
– value zero stands for resonance tuning. The optional current injection feature calculates the resonance point.
When current injection used, not necessary move the coil determine the tuning
point. necessary,
the regulator then positions the coil the determined tuning point.

Parameters Description
% The percent value relates the resonance current Ires. But the resonance point exceeded, the ac-
tive current and the voltage the grid's resonance point will determined the
considerably more accurate method.
0 Minimum adjustment dIpos:
In order estimate the resonance curve, the P-coil must undergo minimum adjustment
in order obtain sufficient reference points for the calculation.
Parameters Description
YES Resonance peak must exceeded
NO Resonance peak must not exceeded
.
– Positive values stand for overcompensation (the P-coil supplies more current when
an earth fault occurs than the grid’s capacitances overcompensation)
– Negative values stand for undercompensation. the resonance point not exceeded, the method will only able to
estimate the value the resonance current.3.
