Abstract

Abstract: The Pmac 801 intelligent protection controller was introduced. According to several accidents occurred in the power plant, the motor control circuit, which includes low voltage 380V molded case circuit breaker plus contactor with Pmac 801 intelligent protection controller, was analyzed theoretically. Some existing problems were pointed out, and the solving methods were put forward.
