Monitors changes in transformer oil
07 April 2015
Vaisala's Moisture, Hydrogen and Temperature Transmitter MHT410 continuously monitors changes in high-voltage transformer insulating oil and provides accurate real-time measurements and trend data which facilitates reliable decision-making.

The MHT410 swiftly recognises transformer fault conditions allowing customers to resolve potential problems before any further damage is done. Having real-time data also allows for predictive maintenance planning which helps customers minimise service shutdowns and outages.
The transmitter measures moisture, hydrogen and temperature directly in the transformer oil. Due to a special probe design, with an adjustable probe installation depth, the sensors are positioned in direct contact with representative oil in the transformer providing accurate measurements and reliable data.
The MHT410 is built to last; it doesn't have pumps, hoses, batteries or other consumable parts. A non-membrane technology, the hydrogen measurement has no service or replacement needs.
MHT410 integrates three critical measurement parameters in a single probe. Easy to install, the probe is ready to use within minutes. Adjustable probe installation depth fits in a variety of transformer valves to ensure optimal measurement. The unit is maintenance-free, with no calibration or adjustment required after installation.
