DETERMINATION OF DISTANCE TO POINTS OF DOUBLE EARTH CONNECTION AT ELECTRIC POWER TRANSMISSION LINES IN NETWORKS WITH LOW EARTH CURRENTS

摘要

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.1 dwg
