primary fault

In this paper, firstly, based on the analysis of the models of the primary arc and the secondary arc under the temporary single-pole fault, the waveform of the voltage of faulty phase under the different type of fault is simulated by ATP-EMTP.

本文首先分析了单相瞬时性故障情况下的一次电弧和二次电弧模型，利用ATP-EMTP仿真软件仿真得到了不同故障性质情况下的故障相端电压波形；

This paper takes a practical primary fault for an example to analyze and calculate, and illustrates that the fault will spread if the B phase fault were not be cut in time.

以一次实际故障为例，进行了分析计算，说明B相故障可能出现切除不及时导致故障扩大。
