Enabling Smarter Grid Infrastructure
Transformer failures rarely happen without warning. Before insulation breakdown, overheating, or electrical faults occur, transformers release trace gases dissolved in insulating oil. By transforming dissolved gas signals into actionable intelligence, utilities can improve grid reliability, transformer lifetime, and maintenance planning.
Utility Power Transformers
Monitor critical substation transformers to detect early-stage electrical or thermal faults.
Distributed Grid Transformers
Enable monitoring of distribution transformers across urban and industrial grids.
Renewable Grid Integration
Monitor transformers connected to solar and wind infrastructure.
Predictive Maintenance Programs
Use continuous gas monitoring to prioritize inspections and maintenance scheduling.
Asset Lifecycle Management
Extend transformer lifetime by detecting degradation patterns early.
Fleet-Wide Monitoring
Deploy sensors across transformer fleets for centralised visibility into grid health.
How the System Works
Nanomaterial-based sensing for real-time refinery gas analysis.
Fast Sense sensors monitor trace gases dissolved in transformer oil, capturing molecular signatures associated with transformer faults. Selective sensing layers isolate key fault gases while rejecting interfering compounds.
Sensor data is transmitted to monitoring platforms and utility dashboards, where operators can detect trends, identify anomalies, and prioritize maintenance actions across transformer fleets.
