Abstract

Damages of transformer, potential transformer, current transformer, circuit breaker, disconnecting switch, arrester and other kinds of high voltage electrical equipments in substation under different seismic intensities have been summarized based on the damage data of electrical power system during Wenchuan earthquake. Damage probability density function curve and damage probability curve (vulnerability curve) of above high voltage electrical equipments have been established based on seismic intensity through normal distribution function and its accumulated function. Results show that transformer is the most vulnerable equipment which can be damaged in low seismic intensity, next to which are circuit breaker, arrester, PT, CT, disconnecting switch; the damage probability curves of PT, CT and disconnecting switch are very similar.
