Benefits
Transformer Monitoring with Hydrogen Sensors & H₂ Analyzers
Transformers are the backbone of both utility grids and industrial facilities. Yet undetected faults can cause dissolved gases like hydrogen (H₂) and methane (CH₄) to build up inside transformer oil. This buildup signals early warning signs of arcing, overheating, or insulation breakdown.
Traditional dissolved gas analysis (DGA) is done via periodic sampling — costly, time-consuming, and reactive. Fast Sense provides a continuous, real-time hydrogen sensing solution that transforms monitoring from reactive to predictive.
Why Hydrogen Sensors Are Critical for Transformers
- Hydrogen is the earliest marker of transformer faults. Even trace ppm-level increases indicate stress.
- Methane and CO₂ trends help distinguish between thermal and electrical faults.
- Utilities typically operate tens of thousands of transformers worldwide — any outage can mean losses of $5,000–$10,000 per hour in downtime for industry, and far more for utilities.
By deploying Fast Sense H₂ analyzers, operators can extend transformer lifespan, reduce unplanned failures, and safeguard infrastructure.
Technical Deep Dive: H₂ Sensing in Transformers
Our probe-type hydrogen sensors measure dissolved gases in transformer oil directly.
- Placement: installed in sealed tanks, underground vaults, or substation transformers.
- Range: detects 0–100% H₂ with ±3–5% FS accuracy.
- Cross-sensitivity: designed to ignore background gases like O₂ or CO₂.
- Durability: resistant to oil contamination, humidity, and pressure fluctuations.
Compared to infrared or catalytic sensors, Fast Sense’s chemical-resistive nano-sensor array delivers stability and longevity with minimal recalibration cycles.
Case Studies
- Utility Grid Example: A large European operator avoided a $5M transformer outage by detecting hydrogen spikes days before a breakdown.
- Industrial Example: A mining facility extended transformer life by 10 years through continuous dissolved gas monitoring.
Industry Data
- The global transformer monitoring market is projected to exceed $3.5B by 2030.
- Over 10 million transformers operate worldwide in grids and industrial plants.
- 50% of transformer failures are linked to undetected gas buildup.
- Utilities lose an estimated $150B annually to power outages, much of it due to transformer failures.

FAQ's
Can hydrogen sensors detect both dissolved and leaked gases?
Yes. Fast Sense solutions combine dissolved gas analyzers for oil with leak detection sensors for cabinets and vaults.
How do H₂ analyzers compare to traditional DGA?
DGA is periodic and reactive. Fast Sense analyzers provide continuous, real-time data.
What’s the lifetime of these sensors?
Our hydrogen sensors last 5+ years with minimal recalibration.
Are they SCADA-compatible?
Yes, multiple interfaces (USB, Modbus, 4–20 mA, BLE).
