Abstract :
This paper introduces very fast transient over-voltage caused by disconnecting switch operation of GIS. ATP-EMTP simulation program is applied to analyze the very fast transient over-voltage of 500kv GIS substation. The effect of protection measures on equipments is compared and analyzed, such as adding opening and closing resistor, R-C absorber, and Ferrite Rings. Also the measures are analyzed with considering the actual situation. This research thinking takes safety and economy into account, which can provide new reference for the engineering.
