Electric power is crucial during the aftermath of earthquakes to ensure the continuous operation of disaster management and emergency services. Furthermore, any disruption in electrical power can result in significant economic losses due to the downtime of critical facilities. Hence, it is of utmost importance to maintain the seismic safety of electrical power systems and their components. Seismic regulations and standards already exist for electrical power systems, particularly in the United States of America (USA) and Europe. Similarly, Turkey has recently developed a similar regulation set to take effect in 2024. This study focuses on the current practices related to assessing the seismic suitability of electrical equipment in power stations and implementing the regulations for seismic qualification of these systems. Among the various electrical equipment, circuit breaker has been chosen for case study. The seismic assessment of the selected high voltage equipment has been conducted according to the new regulation under the seismic hazard specifically defined for Turkey. The case study demonstrates a novel approach to assessing and categorizing the seismic response of high-voltage electrical equipment, offering insights into how circuit breakers are expected to behave when subjected to earthquake-induced forces.
