In-line hydrogen-in-oil probe sensor for transformer monitoring
The Challenge
Expensive Tests, Dangerous Gaps
Traditional dissolved gas analysis (DGA) remains the gold standard for transformer health monitoring — but the operational reality is far from ideal. Systems are expensive, maintenance-heavy, and fundamentally periodic rather than continuous.
Between tests, critical fault signals can develop undetected. Incipient failures in winding insulation, overheating conditions, and partial discharge events generate characteristic dissolved gases — but if no one is measuring, no one knows.
As grid infrastructure ages and loading patterns become more complex, the gap between what transformers need and what legacy DGA systems deliver continues to widen.
The Fast Sense Approach
Lighter, Continuous, Scalable DGA
Fast Sense reimagines dissolved gas analysis as a lighter, more continuous sensing capability — designed to be deployed more broadly across transformer fleets rather than reserved for only the most critical assets.
By providing continuous dissolved gas awareness with a simplified deployment model, Fast Sense enables earlier fault detection, smarter asset management, and a more scalable approach to transformer intelligence across the grid.
How It Works
From Sensing to Decision
Step 01
Continuous DGA Sensing
Monitor dissolved gases continuously — not periodically — for real-time transformer health awareness.
Step 02
Fault Indicators
Track key dissolved gas ratios that indicate incipient thermal, electrical, and chemical faults.
Step 03
Early Warning
Detect degradation patterns before they escalate into costly failures or outages.
Step 04
Simplified Deployment
A lighter monitoring approach designed for broader fleet deployment, not just critical assets.
Why It Matters
Measurable Operational Impact
Earlier Fault Detection
Identify degradation signals between traditional test intervals.
Lower Monitoring Burden
Reduce the cost and complexity of transformer health monitoring.
Smarter Asset Management
Make data-driven maintenance decisions across the transformer fleet.
Reduced Maintenance Complexity
Shift from scheduled overhauls to condition-based interventions.
