Hydrogen (H2) Measurement and Monitoring
Why to Measure Hydrogen?
Hydrogen is a general gas that is generated in various transformer faults. Hydrogen measurement is used for example as a simple early warning indicator in power transformers before actual failure occurs.
What Makes Our Hydrogen Measurement Unique?
The Vaisala MHT410 combines a pair of thin film sensors with a temperature sensor to provide direct real-time measurement of the Hydrogen and Moisture in oil. Most importantly, by using the sensors in line in the oil, you get long-term field operation with no consumables or maintenance costs.
- Hydrogen measured directly in oil.
- Humicap® Sensor measures true relative saturation (%RS) in oil.
- Highly selective sensors immune to oil contaminants.
- No membrane or other consumables.
- No pumps or mechanical parts to maintain.
