Abstract
This article presents the design, seismic simulation, and seismic testing of a 2500 kVA 36 kV 7.7-ton dry-type transformer designed to withstand the rigorous IEEE693-2018 moderate-level seismic test involving dynamic forces in the range of 0-55 Hz and 0.5 g acceleration. The testing was conducted at IAGB Test Company in Munich, Germany, and we are pleased to report that the test was successfully completed. Remarkably, the transformer design eliminates the need for additional consoles or supports, achieving stability solely through the use of eight M24 fasteners for secure grounding. This innovative approach ensures the transformer’s resilience under seismic conditions, addressing critical considerations for power infrastructure in earthquake-prone regions. The results and implications of this seismic testing contribute valuable insights to the field of transformer design and seismic resilience.
