국내외 자산관리 기술 동향을 고려한 25.8kV 옥내용 노후 GIS 차단기의 건전도 평가에 관한 연구

This paper investigates the transition from TBM (Time-Based Management) to CBRM (Condition-Based Risk Management) in global asset management trends, underscoring the importance of prioritizing asset condition in decision-making. Domestically, strategies that rely heavily on asset lifespan often result in the premature replacement of assets still in optimal condition, leading to inefficiencies. This study assesses the condition of a 25.8kV indoor GIS (Gas-Insulated Switchgear) circuit breaker, which had been in operation for 27 years and replaced under outdated management criteria. The assessment found that most of these assets were in excellent condition, highlighting the unnecessary financial and resource waste from replacing optimally performing assets. These findings advocate for a paradigm shift to a CBRM-focused strategy, indicating that such an approach could enhance economic and operational efficiency, extend asset lifespans, reduce environmental impact, and improve sustainability.
