Abstract

PURPOSE: To stably detect the generation of abnormal currents in power circuits with a simple circuit constitution by connecting the d.c. side terminals of two sets of 3-phase halfwave rectifying circuits to one of terminals of lumped resistors and the mutually connected secondary terminals of current transformers to the other terminal.
