Abstract :

Circuit eakers are expensive and vital equipments in substations; thereby calls for safe functioning of these equipments, especially during limit conditions, like earthquakes. This paper describes the verification of HV circuit eaker with OM according to IEC TR 67721-300 AF5. The verification has been performed using FEA software Ansys. The paper describes the basic facts about the analyzed eaker as well as the considered load cases and its results. Seismic analysis by well-known ‘response spectrum method’ yields reliable results only when correct values of natural frequency and damping or fraction of critical damping of the structure are available. Therefore, it is important to first extract the natural frequencies and Corresponding mode shapes for first few dominant modes.
