摘要

Tall and slender substation equipment is prone to failure under seismicexcitations. The consequences of such failure can be devastating andlead to weeks or months of lost power.The IEEE Std 693-2005 ensures that all substation equipment installedin high seismic areas are designed to withstand earthquakes of aseverity related to that area.There are numerous ways to increase the seismic strength of substationequipment and this paper will discuss doing so by base isolation,specifically using wire rope isolators (WRIs).
