Abstract
To reduce the damage on power system and electrical devices caused by hidden faults in protective relaying equipments and its secondary circuit, and to ensure the safe and steady operation of electric power system, two cases occurred in Brazil and Guangdong Grid are analyzed respectively. Hidden faults are sorted and assessed according to their features, and some counter-measures are proposed to provide some reference on controlling the hidden faults in relay protection.关键词
