Original Abstract

The paper describes new method of elimination phase capacitance asymmetry by ancillary suppression coils. This method has favorable effects on the network operation during the ground fault and do not reduce the protecting elements sensitivity to high-ohm ground faults. By improving the accuracy of the arc-suppression coil tuning the safety of the compensated networks operation can be enhanced. The new method of elimination of the phase asymmetry opens the secondary advantage like new method of fault location. This location method starts from idea of fault location using inter-harmonic signal or remote control signal and is based on injection of higher inter-harmonic frequency signal to the secondary windings of ancillary suppression coil which is connected to affected phase
