Discussion on Leakage Protection in Distribution Network

Abstract

Although the voltage level of distribution network is low, the variety of power equipment is complicated, the users are uneven, and there is a greater risk of electric shock. The problem of leakage in distribution line are discussed. First of all, the leakage protection is systematically analyzed, then the correct use of leakage protection in distribution network is studied. Finally, the common problems of leakage protection are expounded from the human level and material level. The solution suggestion is given. The research of leakage protection is of great significance to promote the application of leakage protection. The purpose is to make the staff understand the correct use of leakage protection, which has certain promotion value.

A Study on DC Limit Parameters in RCD Operation Using Capacitor

“…In general, a 30-mA rated current is used as the standard limit value following the IEC standard. In common electrical installation for buildings, TT networks where both RCD and Earth grounding are used [4]. However, although electrical shocks can be avoided with that kind of insulation, some false trips might be also occured.…”
