Newly Proposed Seismic Criteria of Transmission and Substation Equipments

송변전기기의 내진설계기준 제안

A new seismic design criteria of electric transmission and substation facilities has been proposed. For this propose, the historic data of the earthquake damage and the state-of-the-art of the facilities were carefully reviewed and evaluated. Based on the results, a most reasonable and efficient design criteria has been extracted and proposed for the practical design of the facilities. The criteria is expected to be effectively used for obtaining the seismic safety of newly constructed or extensioning facilities. However, an independent criteria is required to evaluate and improve the seismic capacity of existing facilities
