The evaluation of the seismic stability of electrical equipment is very important in substation. In this paper, the influence of support on seismic response and vulnerability of voltage transformer is studied., First, the support-voltage transformer finite element models(FEM) is established by Abaqus. Natural frequency, dynamic amplification factor of support-voltage transformer with different PGA are investigated. Afterwards, the seismic response parameters obtained by FEM simulation are applied to the vulnerability analysis of voltage transformers. Finally, the vulnerability result indicated that support height and ceramic material have significant effects on the probability of equipment failure.
