| Abstract |
This study proposes a life extension strategy for GIS (Gas-Insulated Switchgear) in response to the growing economic and environmental pressures faced by the Korean power industry. Based on an analysis of ageing mechanisms and field condition assessments for components in GIS, each component was classified into three tiers: repairable, refurbishable, or requiring replacement. Additionally, Economic and environmental sustainability were quantitatively evaluated. Results show that extending the service life by ten years reduces depreciation costs by over 30%, while deferring CO₂ emissions by approximately 10.2 tons per GIS bay. The study also addresses limitations due to outdated specifications, suggesting practical solutions such as operational condition verification and overseas market expansion. Building upon insights from Part 1, this paper offers a technical framework that supports Korea’s carbon neutrality and capital efficiency goals through systematic of life extension. |
