Transformer and Substation Condition Monitoring
- Challenge
- Limited early visibility into incipient transformer and substation faults
- Reactive maintenance leading to unplanned outages and high repair costs
- Difficulty correlating data from tank, winding, OLTC, bushing, and cooling systems
- Overloading impacts not quantified against asset health and remaining life
- No unified enterprise view of transformer performance across substations
- AIGC Solution
- Implemented a comprehensive online Condition Monitoring System (CMS) for transformers and substations
- Integrated real-time monitoring of main tank, windings, OLTC, bushings, cooling systems, and partial discharge
- Applied advanced analytics and health indices to correlate thermal, electrical, and mechanical parameters
- Enabled centralized dashboards for asset health scoring, alarms, and trend analysis
- Connected CMS to Enterprise Asset Performance & Management systems for lifecycle visibility
- Realized Value
- Early detection of failure modes, preventing catastrophic transformer damage
- Reduced maintenance costs through condition-based and predictive maintenance
- Improved reliability by assessing and managing overloading impact on transformer health
- Improved reliability by assessing and managing overloading impact on transformer health
- Extended asset life by timely intervention on degradation indicators
- Gave operations and asset teams a clear, real-time view of transformer risk and performance
