METHOD OF FINDING OF DISTANCE TO PLACES OF EARTH FAULTS ON TWO POWER LINES IN NETWORKS WITH LOW EARTH FAULT CURRENTS Russian patent published in 2015 - IPC G01R31/08

Abstract RU 2558266 C1

FIELD: electricity.

SUBSTANCE: method consists in measurement of active and reactive components of zero sequence current and phase voltage of damaged lines in emergency mode and subsequent calculation of inductive resistance to each place of earth fault proportional to the distance to places of damages.

EFFECT: improvement of accuracy of finding of distance to places of double earth faults on power lines.
