Safety Investigation and Improvement Suggestion of Old Residential Community Electricity Consumption

Li Guangxi Feng Tao

Abstract: Sampling survey was carried out on the low voltage distribution system in the old residential community of one city. The survey shows that most of the old residential community have some hidden safety problems. The grounding form and the risk of electric shock of low voltage distribution system in sample residential community are analyzed by modeling. Based on the economy and practicability, some suggestions have been put forward for the grounding type of low-voltage distribution system, the selection of RCD, the shock protection of bathroom and so on.

Keywords: old residential community; earthing form; residual current operated protective device; contact voltage; local equipotential bonding;
