3 phase closing overvoltage and single phase reclosing overvoltage in Yangcheng Jiangsu 500 kV power transmission system by EMTP is presented in this paper.The results show that the power frequency overvoltage is within the extent of design criteria
secondary arc current smaller than 10 A enables single phase reclosing to be successful
both colsing resistors and MOA can be used in the line protection to limit the closing overvoltage effectively.
