DETERMINATION OF DISTANCE TO POINTS OF EARTH CONNECTION AT TWO ELECTRIC POWER TRANSMISSION LINES IN NETWORKS WITH LOW EARTH CURRENTS Russian patent published in 2015 - IPC G01R31/08

Abstract RU 2557375 C1

FIELD: instrumentation.

SUBSTANCE: proposed method consists in measurement of active and reactive components of phase current and voltage under emergency. Then, inductive reactance is calculated to every earth point proportional to distance to pints of faults.

EFFECT: higher accuracy of determination.
