СПОСОБ ИЗМЕРЕНИЯ СОПРОТИВЛЕНИЯ ЦЕПИ ЗАЗЕМЛЕНИЯ ОПОР КОНТАКТНОЙ СЕТИ

摘要

FIELD: measuring engineering. ^ SUBSTANCE: proposed method for measuring the resistance of the grounded circuit of a contact-line supporting structures is based on measurement of potential differences and current strength by means of one instrument at the reswitching rate, at least twice exceeding the potential variation rate on rails. ^ EFFECT: the technical result of the invention consists in increasing the resistance measurement accuracy. ^ 1 cl, 2 dwg
