Asset management in power industries is crucial for maximizing asset value by considering life-cycle data and ensuring reliability and cost-effectiveness. This paper addresses the paradigm shift in asset management strategies from traditional approaches to Condition-Based Risk Management (CBRM). Unlike international practices, South Korea relies on Risk-Based Replacement (RBR), which assesses risk based on equipments years of service, leading to premature replacements of Gas-Insulated Switchgear (GIS) without considering equipment condition. Consequently, asset value maximization is hindered. To address this, the paper evaluates the degradation characteristics and health condition of aging GIS O-rings used for approximately 27 years. The collected O-ring samples were in excellent condition. The findings contribute to efficient maintenance cycle determination and the establishment of economical and efficient power facility asset management strategies.
