  1. The single phase - to - grounding fault frequently occurs in neutral ungrounded system. the fault line must be found to avoid a phase - to - phase fault. in this paper, firstly, the condition on single phase - to - grounding fault occurring in neutral ungrounded system are discussed and then the main troubles in choosing fault line are pointed out

    本文首先分析了小電流接地系統發生單相接地故障時的情況，指出選線所遇到的主要困難，進而對小電流接地系統單相接地故障的選線及測距的方法做了比較和綜述。
  2. For fire grounding, grounded impedance varies greatly because of air dissociation, and this causes protection set to startup and resume again and again. therefore, the main protection of the fault line ca n ' t cut off the fault quickly and accurately, and may lead to overstep tripping of near lines " protection sets and eventually cause more serious faults on the power system

    同時故障電流一般比較小，電流突變也很小，有時呈緩慢上升的變化趨勢，對火焰接地來說，由於空氣游離的緣故，接地阻抗變化很大，使現有保護反反復復啟動、恢復，可能會導致相鄰線路、設備的保護越級跳閘，使電力系統出現更嚴重的故障。
