本レビューは、SF6を使用するガス絶縁開閉装置（GIS）の脱炭素化を、ガス代替だけでなく漏洩検知・回収・在庫管理・予知保全・リスクベースの寿命延長を統合した運用枠組みとして提示する。2020〜2025年の研究を整理し、赤外・多チャンネル光学検知や部分放電診断、データ駆動モデル、ヘルスインデックスが保守優先度と更新判断を支えることを示す。サウジアラビアの高温・多塵・分散立地という条件に合わせ、炭素と信頼性を結合したシステムとしてスマートGISを統治すべきと結論づける。
English
This review reframes GIS decarbonisation beyond SF6 substitution, integrating leakage detection, gas recovery and inventory control, predictive condition assessment, and risk-based asset-life extension. Synthesising 2020-2025 research, it shows infrared/optical leak localisation, partial-discharge diagnostics, data-driven models and health indices translate condition evidence into maintenance and refurbish-vs-replace decisions. For Saudi Arabia's hot, dusty, dispersed grid, it argues smart GIS should be governed as a coupled carbon-reliability system.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でもSF6は排出係数・Scope1管理の重要対象であり、電力・重電各社の脱炭素と設備更新投資判断に直結する。漏洩検知・回収・予知保全の統合枠組みは、SSBJ開示におけるScope1削減策や設備の長期リスク管理の記述に応用可能。
In the global GX context
SF6 is among the most potent GHGs, and this paper's coupled carbon-reliability framing speaks to global TCFD/ISSB disclosure of Scope 1 abatement and asset resilience. It offers a template for utilities in emerging and hot-climate grids to link gas inventory control with transition planning, complementing EU F-gas regulation debates.

📄 Abstract（原文）
Gas-insulated substations and switchgear (GIS) offer compactness, reliability and environmental protection, but the continued use of sulphur hexafluoride (SF6) creates a material climate-management obligation because small losses can dominate the greenhouse-gas footprint of otherwise efficient high-voltage assets. This review develops an integrated low-carbon operating framework for Saudi GIS portfolios by connecting four practices that are commonly managed separately: leakage detection, gas recovery and inventory control, predictive condition assessment, and risk-based asset-life extension. A structured integrative review of peer-reviewed research published from 2020 to 2025 was conducted across recent SF6-alternative, leakage-monitoring, partial-discharge, digital-twin, health-index and lifecycle studies. The evidence indicates that decarbonisation cannot be reduced to replacing the insulating gas. Existing fleets require accurate leak localisation, closed-loop gas handling, condition-informed interventions and disciplined decisions about refurbishment versus replacement. Infrared and multi-channel optical methods improve non-contact leak identification, while decomposition sensing, vibration analysis, partial-discharge diagnostics and data-driven models broaden the observable condition state. Health-index and condition-based risk-management methods then translate heterogeneous evidence into maintenance priorities and life-extension decisions. For Saudi Arabia, the proposed architecture is designed for hot, dusty, geographically dispersed and rapidly modernising grid environments, where outage avoidance, technician capability, spare-parts strategy and emissions stewardship must be considered together. The review concludes that smart GIS should be governed as a coupled carbon-reliability system in which gas balance, defect evidence, intervention history and remaining-life decisions continuously update one another.
