The study of lightning-protection grounding for power dispatching and communication equipment

Because of irrational grounding, the normal work of dispatching and communication equipment is affected heavily, equipment can even be destroyed. The grounding problem for power dispatching and communication equipment in microwave buildings is analyzed in the paper. A comparison between separated and common grounding in different cases is made. An optimal grounding scheme is proposed according to the actual situation. This is of practical significance and theoretical study value for lightning-protection and anti-interference for specially sensitive automation equipment to the outside interference.
