Vaisala Launches Reliable Moisture, Hydrogen and Temperature Transmitter for Online Transformer Condition Monitoring



High voltage transformers are a critical component in the generation and transmission of electricity. Today the power industry is facing the challenges of end-of-life equipment, impacts of overload situations, and an increasing number of faults in the network. All of these have significant consequences to the operation of transformers, and increase the risk of unexpected failures and outages. Through efficient monitoring however it is possible to successfully mitigate these issues. For example, by measuring the hydrogen content in transformer oil, as well as the speed of its formation, utilities can detect and assess the severity of a fault situation. Furthermore, moisture dramatically affects the life of a transformer; elevated moisture in oil levels accelerates the ageing of transformer insulation paper as well as the oil's ability to act as an insulator. Moisture content can change quickly and should be monitored to ensure reliable operation.



Vaisala's Moisture, Hydrogen and Temperature Transmitter MHT410 continuously monitors changes in high-voltage transformer insulating oil. Vaisala's unique probe solution allows the device to provide accurate real-time measurements and trend data which facilitates reliable decision-making. The MHT410 swiftly recognizes transformer fault conditions allowing our customers to resolve potential problems before any further damage is done. Having real-time data also allows for predictive maintenance planning which helps our customers minimize expensive service shutdowns and outages.



Reliable measurement thanks to unique probe design and robustness



Unlike conventional solutions, the MHT410 transmitter measures moisture, hydrogen and temperature directly in the transformer oil. Due to an innovative 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. Thanks to the robust design and reliable measurement technology the MHT410 makes false alarms a thing of the past.



Intuitive and easy to install



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.



MHT410 will be available summer 2015.
