Experimental Seismic Response of High‐Voltage Transformer‐Bushing Systems

This paper describes the shake table testing of a full-scale high-voltage electrical transformer-bushing system. The main objective of the study was to investigate the amplification between the ground motion and the motion at the base of the bushing under various ground-motion time histories and intensities. Another objective of the testing was to assess the predictions of a three-dimensional finite-element model of the transformer-bushing …
