Seismic Evaluation Method of UHV Transformers for Soil-structure Interaction

China is an earthquake-prone country. In recent years, Wenchuan earthquake and other earthquakes have caused serious damage to power facilities. As the most important electrical equipment in UHV substations, transformers are facing great threat of disasters. Currently, seismic evaluation does not consider soil-structure interaction, which conducive fine design transformers. Based on structural features transformer equipment, method with interaction proposed this paper, provides a basis for performance transformer.
