为了对不成功的单相重合闸进行分类，本文对德国输电网中成功和不成功的单相重合闸的故障记录进行了研究。为了分析故障录波，提出了一种确定潜供电弧熄灭时间的新方法。文中还提出了一种区分电弧故障和其它故障的扩展方法。这两种方法都是基于对故障相断开后故障线电压波形和频谱的分析
To classify unsuccessful single-phase autoreclosures, in this paper fault records of successful and unsuccessful single-phase autoreclosures in a German transmission network are investigated. In order to analyze the fault records, a new method is developed to determine the time of secondary arc extinction. An extended method to distinguish between arc faults and others is also presented. Both methods are based on analyzes of the waveform and the spectrum of the faulty line voltage after the opening of the faulted phase
