Seismic Design Response Spectra for Electrical Substation Equipment from City of Los Angeles, 1988 . Seismic standards and technical manuals are also published by military agencies. These include the Tri-Service manuals Seismic Design for Buildings,1982, and Seismic Design Guidelines for Essential Buildings, 1986, which contain amendments to the SEAOC Tentative Lateral Force Requirements, 1985, which are specifically applicable to flexible or flexibly mounted mechanical and electrical...

Electrical Transmission And Distribution Systems

Electrical power transmission systems can be divided into four subsystems substations, which according to past experience are vulnerable to seismic damage transmission lines, which in the past have not been very vulnerable to earthquake damage distribution systems which are also not very vulnerable to earthquakes and control and backup facilities which are occasionally damaged because of inadequate tiedown and support systems. Substations fall into several categories Transmission substations...
