Neutral zone closing overvoltage characteristics analysis in traction power supply system for group trains

电力工程技术
During the operation of group trains, the trains frequently pass through the neutral zone. Then, the generated closing overvoltage will cause serious insulation damage to the traction power supply system and the trains′ high-voltage equipment box.
