Abstract |
|
A transformer is a major equipment of electrical power system. Its proper functioning is essential for uninterrupted power supply. Certain past observations have revealed that transformers are more vulnerable to earthquakes as compared to other power equipment. An in depth study of the behavior of transformer, its stressing, and deformation in critical parts is extremely essential. A 33kVA transformer was analyzed for seismic effects using the Response Spectrum Method and the design response acceleration curve. The finite element based software ANSYS was used to analyze the structure; using three different mode combination methods, i.e. SRSS, CQC and ROSENBLUETH. The main purpose of the study, being to compare the relative predictions of the three mode combination methods for the state of stress and component deformation in the transformer. |
