摘要
用相量图分析的方法,当电压互感器PT二次侧B相接地时,在正常运行状态和电力系统中发生单相接地。
Using phasor diagram to analyze the consistence of self_produced 3 0 and out_connected 3 0 of microprocessor_based protection at normal operation condition or single phase earthing or two phase short_circuit or two phase earthing short_circuit when B phase earthes on secondary side of PT.
