| Abstract: | In this paper the performances of a German 1140 current leak age protection system has been allsidey systematically analysed.Al- though it is more perfect so far.there exist some potential- ly unsafe factors to a current leakage breakdown in a certain range.In addition,a solution to the problems of china-made ones has also been directed in the paper. |
