Abstract :
Based on Tian huangping GIS Substation, very fast transient over-voltage caused by disconnecting switch operation of GIS is simulated and calculated in this paper with ATP-EMTP program. The effect of protection measures on equipments is compared and analyzed, such as adding opening and closing resistor, MOA, R-C absorber, and Ferrite Rings. Also the measures are analyzed with considering the actual situation, which can provide reference for the implementation of the practical project.
