Analysis of 10kV Grid Arc Grounding Over-voltage Hazards and Countermeasures

摘要：

　　Through the analysis of 2 single-phase grounding over voltage accidents caused by capacitive over current in 10 kV power grids in this paper, the causes and damages of arc grounding over voltage are illustrated, and the necessity of capacitive current test and effective methods are pointed out. The test and assessment to the 29 substations capacitor currents provides a scientific basis for the correct selection of the neutral point operation mode, and the strengths and weaknesses of the neutral Point grounding through the arc suppression circle and the mode trends of 10kV grid neutral grounding are demonstrated.
