Abstract By means of ATP-EMTP electro-magnetic transient program, a comparative analysis of numerical simulation experiment for the electronic equipments to use the grounding wiring modes that shares a same network and common busbar with a same network but not common busbar is carried out . It is concluded that，it is safer for electronic equipments to use the grounding mode with same network but not the common busbar than to use the grounding mode with same network and common busbar.
