| Abstract: | According to the analysis of the insufficiency of low voltage electrical network leakage protection system of mine presently, the new selective leakage protection mothod based on power line communication was proposed, and the composition and principle of the installment was introduced in detail. The experiment proved that the leakage protection system has merits of strong real-time,exact judgement of selectivity and high reliabitity. |
