The heavy seismic damage to the electrical equipment has been brought, it is necessary to study the seismic performance of electrical equipment. According to the GB 50260-1996 Code for seismic design of electrical installations, the basic contents and steps of seismic response analysis for the electrical equipment calculation by mode decomposition and response spectrum theory are described. The seismic performance of 500kV current transformer is analyzed by using material strength failure criterion. The results show that the 500kV current transformer is able to satisfy the serviceability requirement in seismic intensity 9 regions. According to the position of danger section , several measures to improve the seismic performance of the current transformer are put forward, which could be for reference of seismic design for other electrical equipments.
