INVESTIGATION OF BLOCKING ALGORITHM FOR TRANSFORMER CURRENT PROTECTIONS IN MAGNETIZING INRUSH CURRENT MODES

Abstract

Presents investigations on blocking  algorithm for transformer  current  protections  during magnetizing  inrush  current. The investigations have shown that the algorithm has high sensitivity and reliably determines magnetizing  inrush current modes.
