Abstract

In order to evaluate the structural safety from an earthquake, the seismic analysis of large structures such as GIS in electric power substations and equipments for nuclear power plant has been carried out because the seismic qualification by experiment is very expensive. This paper presents the seismic analysis of the 72.5kV GIS produced by LGIS. The finite element model of the GIS is developed and analyzed using ANSYS. The model consists of beam elements for the enclosures and mass elements for the conductors and the mechanisms. Using the transient analysis under seismic load, the structural safety is verified.
