Overvoltages and insulation coordination of 1000‐kV AC transmission systems in China

SUMMARY Overvoltages and insulation coordination requirements of 1000-kV AC transmission systems in China are introduced. On the basis of the single-circuit transmission project, which has been put into operation since 2009, and the planned double-circuit transmission projects, the control of temporary overvoltage and switching overvoltages and the determination of the rated voltage of metal oxide arrester are presented. The lightning protection measures for transmission lines and substations are given. Determination of insulation level of substation apparatus and clearance of external insulation for transmission lines and substations are provided. Copyright © 2011 John Wiley & Sons, Ltd.
