Abstract

The seismic evaluation of electric power facilities in the switchyard of nuclear power plants is currently insufficient. In order to evaluate theseismic performance of lightning arrester subjected to four types of earthquake (near- and far-fault earthquakes, NEHRP Site Class A&Band D earthquakes), seismic fragility analysis using maximum likelihood estimation is performed considering various damage states. Thecomparison of the seismic fragility curves for three main parts of lightning arrester that are the busing, anchor and steel frame, reveals thatthe failure of lightning arrester is governed by the bushing damage mode such as porcelain cracking.
