Abstract
Recent moderate and strong California earthquakes have demonstrated that parts of power systems are very vulnerable to damage. Most damage has been due to the failure of porcelain elements in high voltage substation equipment. However, performance is strongly influenced by specific equipment designs and installation practices. There has also been damage to substation buildings, conductor support structures, cast aluminum hardware used on both low and high voltage equipment, equipment support structures, equipment anchorage, and parts of power generating stations. The performance of some communication and control systems has been impaired after earthqakes. The purpose of this guide is to document methods to improve the earthquake response of electric power systems.
