MHT 410 System for analysis of dissolved gases and moisture in transformer oil - Vaisala
The MHT 410 monitoring system allows continuous monitoring of moisture and dissolved hydrogen in transformer oil.Hydrogen is one of the main indicators of developing defects in a transformer; its control will significantly improve the reliability of the power transformer.
Data is transmitted via the appropriate communication protocol (see table) or displayed on the Indigo 500 display module, which is installed in close proximity to the sensor.
Peculiarities:
- connection to one valve and direct measurement of moisture and hydrogen in oil
- ease of installation and commissioning
- Works with mineral and natural or synthetic essential oils
- industrial design
- does not require maintenance
