摘要

FIELD: measuring equipment engineering, in particular, engineering of equipment for determining maximal capacitive current of one-phased short circuit with ground.;SUBSTANCE: to achieve result during process of periodic compensation of capacitive current of one-phased short circuit of network with ground first measurement is performed for voltage of neutral line shift and readjustment of rector branches. Second measurement of neutral line shift voltage is then performed. During that in process of another compensation of capacitive current of one-phased short-circuit with ground with first and second measurement of voltage of neutral line shift current through reactor is jointly measured as well as phase shift angle for voltage of neutral line shift relatively to reactor through current, shift angle by phase of parallel phase voltage of network in phase with additional capacity relatively to current through reactor, phase voltage of network and network frequency.;EFFECT: improved precision of determining of maximal capacitive current of one-phased short circuit with ground.;1 dwg
