A new principle for high resistance earth fault detection during fast power swings for distance protection

The combined effects of a high impedance ground fault condition and a fast power swing condition cause the apparent impedance 'seen' by power system distance protection schemes to vary over a wide range. Previous research work has shown that the detection and location of high impedance fau...
