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.
