Description
Summary:The paper resumes the main results of the seismic risk and reliability analysis of an Italian high voltage open air power station, which suffered a significant earthquake in 1976 [1]. The probabilistic estimation of the costs of restoration of the electrical components damaged by the earthquake has been compared with the ones relevant to the installation of anti seismic devices. The main results of an EC partially funded research project [2] dealing with the seismic mitigation of a Gas Insulated Station by means of a Rolling Ball type isolation system are described in the following. 1. Introduction Many recent seismic events have clearly indicated that, without appropriate precautions, a major earthquake may damage important parts of the electric transmission and distribution networ
