| Abstract: | In this paper, the advantage and disadvantage of the pulse action leakage protection are introduced, mainly focusing on the theoretical analysis of the existence of non-protective area. And the leakage current is divided into gradually varied current and mutative current to measure the two. We adopt reasonable solution -- by detection method to solve the problem of non-protective area. So the security and reliability of electric ieakage protecting are enhanced. |
