MAGNETIZING INRUSH CURRENT SUPPRESSION DEVICE FOR TRANSFORMER AND CONTROL METHOD OF SAME

摘要

To provide a magnetizing inrush current suppression device for transformer and control method of same, which accurately calculates the residual magnetic flux when a transformer installed in a non-solidly earthed system, is interrupt by circuit breakers, and which enables suppression of the magnetizing inrush current occurring when three single-phase circuit breakers or single-phase circuit breaker s are used for simultaneously supplying power to three phases of the
