This paper describes a seismic damage estimation method for electric power distribution equipment to support its emergency restoration activity. The predominant factors associated with the seismic damage degree of electric power distribution equipment are classified based on the analysis of its seismic damage record of the 2007 Niigata-Ken Chuetsu-Oki earthquake. Based on the analysis, a seismic damage estimation model is proposed. The proposed model is applied to an actual damaged area and compared to existing damage estimation models used by local governments. Finally, the effectiveness of the proposed model and future subjects are discussed.
