Abstract

FIELD: electrical engineering; relay protection and automatic control of power transmission lines. SUBSTANCE: remote protective gear and fault detector are adapted to operating characteristics of entity under protection by determining complex coefficients of current and voltage correction by the results of two short-circuit experiments and direct correction of currents and voltages in remote protective gear and fault detector. EFFECT: improved operating reliability of protective gear and fault detector.
