| Abstract: | The fault of power system will cause the unbalance of the voltage between the grounding point and far-end zero potential point.And the equipotential net of secondary power system can effectively prevent the occurrence of the lightning damage and false operation of secondary equipment.In the light of the situation that the lightning damages of the computers and electronic equipment in the power plant have increased year by year,this paper analyzes the reasons why the overvoltage can damage the equipment,and ... |
| Keywords: | power plant equipotential grounding network secondary power system lightning damage main grounding network |
