Emergency Treatment in Case of Electric Leakage Protection Device Failure

In the era of technological innovation and development, the State grid system has used a large number of new technologies to improve the performance requirements of the system operation. Because the electricity is one of the People's Daily life and work necessary resources, so in the modern society construction innovation, the relevant state departments for relevant safe hidden trouble, strengthen the supervision of power system, research scholars also put forward in practice to explore a variety of protection device, in order to can reduce the unnecessary accidents. Therefore, based on the understanding of the state grid system operation and leakage protection system research status, this paper proposes a portable non-contact leakage detection device for 400V distribution network, and clarifies the specific measures for the state maintenance, operation and maintenance of distribution network equipment in the new era combined with practical cases.
