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. 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. The optional current injection feature calculates the resonance point. Default setting: 5% The value relates the P-coil's upper end value Imax A. 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. – value zero stands for resonance tuning. When current injection used, not necessary move the coil determine the tuning point. 0 Target detuning: The detuning quantity set this menu.Page 101 Detailed description REG-DP/ REG-DPA parameters Parameters Description % The percent value relates the resonance current Ires. (Warning: possible exceed the self-extinguishing current limit large grids!) A Detuning always has the same absolute value regardless Ires.3 Search method 0 Search method The 'Move coil' method always selected when working without current injection. necessary, the regulator then positions the coil the determined tuning point. Default setting: A 11.1. the resonance point not exceeded, the method will only able to estimate the value the resonance current
