摘要
通过对目前某些选择性漏电保护原理存在问题的分析,提出了一种基于附加直流源漏电检测与零序功率方向型选择性漏电保护相结合的漏电保护原理。
By analyzing the problems for some selective leakage protection principles,the paper puts forward a leakage protection principle based on additional DC source leakage detection combined with the elective leakage protection of zero sequence power direction.
