Защита однофазных потребителей от перенапряжений при обрыве нулевого провода

Abstract

An algorithm of surge protection design for single-phase users under excess phase currents unbalance and N-main break both at the beginning and along the full length of the supply main is studied. It is shown that implementation of such protection in circuit breaker releases is only possible through utilization of wide opportunities of microprocessor technology which allows deeper and more comprehensive analysis of processes in electric mains.
