Performance-based Seismic Evaluation for Pole-Mounted Distribution Equipment

Abstract

In order to restore the electric power distribution system quickly after the huge earthquake, it is important to estimate not only the severe damage but also the minor damage which disturb the quick restoration. In this paper, a method of evaluating a seismic capacity of pole-mounted electric power distribution equipment using shaking table tests is established. In this method, the seismic capacity is defined as a damaged state considering with the restoration efforts and the damaged state is related with seismic intensity. Conducting the shaking table tests using real equipment, we can evaluate the seismic capacity of equipment virtually.
