The preliminary evaluation of the seismic performance of 500 kV capacitor voltage transformer exported to the hydropower station in Los Angeles of America is made through simulation of seismic test on the actual model.The continuous sine wave and sine-wave resonance are input respectively on the prototype through the electromagnetic vibration table.At specified 5 m/s2 earthquake intensity imposed on each set of component of capacitor voltage transformer

each performance parameter meets American standards and the requirements of technical agreement

that can provide a reference for the seismic design of high voltage capacitor voltage transformer.
