0 Target detuning:
The detuning quantity set this menu. The optional current injection feature calculates the resonance point.
Default setting: A
11.
dIpos x(%) Imax
0 Exceed resonance peak:
The exact calculation the resonance curve can only determined exceeding the res-
onance point.
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.
(Warning: possible exceed the self-extinguishing current limit large
grids!)
A Detuning always has the same absolute value regardless Ires.
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
YES Resonance peak must exceeded
NO Resonance peak must not exceeded
.
– value zero stands for resonance tuning.
Default setting: 5%
The value relates the P-coil's upper end value Imax A.
– 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. But the resonance point exceeded, the ac-
tive current and the voltage the grid's resonance point will determined the
considerably more accurate method.3.Page 101
