摘　　要：对于T100s,通过仿真图简要分析了标准制定的依据,并结合试验波形图分析了实际应用。对于T100a,通过标准的介绍,从直流分量和燃弧时间两个方面入手,由仿真图分析提出了以首开大半波和延长大半波开始的几种有效试验情形,并结合燃弧时间的计算,提出了从燃弧时间判断试验有效性的方法。最后,结合试验波形图进行了分析、证明。For the test duty T100s, based on the simulation diagram, the basis of standards are briefly analyzed, and combined with the test waveform diagram, the practical application are analyzed. For the test duty T100a, according to the standard, from two aspects including DC component and arcing time, it is suggested that several valid cases from the beginning of the first phase to clear with major loop and of the extended major loop by the simulation diagram. Through the calculating of the arcing time, the judging method of test validity is put forward. At last, combining with testing oscillogram, analyzed and proved has been carried out.
