摘要
在小电流接地系统中发生单相接地故障的概率要比其他接地故障大得多。而且不及时的排除会引起其它接地故障的出现,并对电力设备的安全构成威胁。本文作者提出一种应用零序电流在短路时的特点和小波分析的方法来确定短路线路。
The probability of single phase-to-grounding in the small current grounding system is much higher than that of anything else. And if it is not eliminated in time, it will lead to worse result. Just as this, finding the faulty in time is very important. In this paper, the author proposes a method to distinguish the feeder by using the hallmark of zero-sequence current in grounding and using wavelet analysis in transient.
