| Abstract: | After the double of the DC system, There are usually instantaneous ground fault. There are even non-correct action of the protective device. This paper finds out the reasons of the instantaneous grounding of the DC system and the hidden safe trouble of the relay protection, and proposes the reasonable solution. |
