DETECTION OF CURRENT CIRCUITS FAULT FOR DIFFERENTIAL CURRENT PROTECTION
ENERGETIKA. Proceedings of CIS higher education institutions and power engineering associations, 2018 False operation of the differential current protection leads to tripping of the most important electrical power objects. Fault of current transformer’s secondary circuits is one of the most often cause of false operation of the differential current protection. Early determination of this malfunction increases the reliability of the differential current
