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.
Why It Matters
Transformer Failures Cause Widespread Grid Outages
A single transformer failure can leave thousands without power for weeks. Continuous dissolved gas monitoring enables early intervention before catastrophic failure.
Periodic Oil Sampling Misses Critical Fault Windows
Traditional DGA relies on monthly or quarterly oil sampling — missing rapid fault development that occurs between sampling intervals.
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.
Product Benefits
Continuous dissolved gas intelligence for grid protection.
Early Fault Detection
Detect molecular signals of transformer degradation before visible failure occurs.
Continuous Monitoring
Move beyond periodic oil sampling with real-time dissolved gas monitoring.
