A test article representative of a piece of high-voltage substation equipment was studied on a shaking table. It consisted of a support structure and an insulator installed on its top. The support structure was constructed from a HSS with well-separated natural frequencies in both horizontal directions. A porcelain insulator typically used on a 230-kV system was used in the study. A set of four wire ropes was used as a seismic isolation for the system. Two installation cases were considered in the study: (1) fixed base and (2) isolated by wire ropes. As required by the latest draft of IEEE693, a number of component tests was conducted to evaluate the performance of the wire ropes. Based on the results of component testing, detailed numerical models of the seismically protected equipment were generated. Each equipment configuration was subjected to seven time histories matched to the same IEEE693 spectrum. Four of them were modified from historical records and matched to the IEEE693 spectrum in the time domain. The other three excitations were synthetic strong motions matched to the same spectrum. The main objective was to evaluate the variability of the seismic response of the equipment subjected to seven time histories matched to the same response spectrum.
