Abstract

The support structure of a surge arrester within the substation is considered for the experimental and finite element study. Support structures are generally used in a substation mainly for the electrical ground clearance purposes but also it protects the mounting equipment with respect to earthquake loads. The paper is aimed to find out the acceleration amplification levels at base of the support structure at severe earthquake loadings even when it is mounted on steel support structures. Seismic tests are carried out experimentally on shake table. The behavior of the support structure is found satisfactory. No material losses are resulted. Finite element studies are also included in the paper. The finite element model predictions are agreeable to the experimental results.
