000009497 520__ $$2eng$$aPower electric substations are key elements of power supply systems. Equipments of the power substations have been the most vulnerable components within the power supply systems in past earthquakes. Damage to substation equipments will cause disoperation of whole substation, and then, widespread power disruptions. This paper develops methods for seismic assessment of medium- and high-voltage power substation equipments. In this paper, data of seismic performance of equipments within fifty-eight medium- and highvoltage substations, as the most vulnerable substations, in past major earthquakes in a few countries are collected. The selected equipments are power transformer, live-tank circuit breaker, dead-tank circuit breaker, disconnect switch, current transformer, potential transformer, bus-bar system, lightning arrester, wave trap, and capacitive coupling voltage transformer. In last part of the paper, a damage ratio curve for the medium and high voltage substations is proposed. The obtained results for damage analyses of the equipments indicate that the live-tank circuit breakers by 32.3% are the most vulnerable equipment and dead-tank circuit breakers by 2.5% have the best seismic performance. Current transformers, bus-bar systems, potential transformers, and power transformers are the other vulnerable equipments respectively.
