Abstract
This report presents a seismic fragility analysis of equipment and structures in an electric substation in Memphis, Tennessee. These include the pothead structure, 115 kv switch structure, 97 kv lightning arresters, control house, capacitor banks, 115/12 kv transformers, 12 kv regulators, 115 kv oil circuit breakers, and 12 kv oil circuit breakers. The results from this fragility analysis provide the expected performance of equipment and structures in a substation. They can also be used to evaluate the seismic performance of the entire electric substation and to perform a system reliability analysis of the electric transmission system.
