How to test high voltage  ? With the rapid development of China’s industrial, agricultural and high-tech industries, the power system 6～66kV power grid is continuously expanding and  extending. Based on the summary of the domestic power distribution network neutral point grounding method for many years of operating experience, the power industry standard DL/T620-1997 ” In “Overvoltage Protection and Insulation Coordination of AC Electrical Installations”, the newly revised and added provisions on the neutral point grounding method, clearly stipulate that the 6～66kV system, when the single-phase ground fault capacitance current exceeds 10A (6～10kV cable line constitutes When the system is 30A), the arc suppression coil grounding method should be adopted. As a result, the use of arc suppression coils in power distribution systems will have more extensive and in-depth application prospects.
