Discussion on the Installation of Residual Current Operated Protective Devices in

Low-voltage Distribution System

 

Abstract Certain technical requirements are needed before the low-voltage distribution system is equipped with residual current operated protective devices. Before installing residual current operated protective devices，the low-voltage distribution system which does not meet installation requirement should be examined and rearranged. This article focuses on the problems to be solved and the corresponding treation methods before installation of residual current current operated protective devices for low-voltage distribution system.

Key words Low-voltage distribution system Residual current operated protective device Neutral point Neutral conductor
