Monitoring probe

The MHT410 swiftly recognises transformer fault conditions, allowing Vaisala's customers to diagnose and resolve potential problems before any further damage is done. This data subsequently allows operators to conduct thorough predictive maintenance planning to minimise expensive service shutdowns and outages.

The MHT410 has a special adjustable probe design that's installed in the transformer oil. This places its sensors in direct contact with representative oil in the transformer providing accurate measurements and data. Information collected by the probe is instantly available to project operators and is designed to integrate seamlessly with most data acquisition systems

The MHT410 is built to last and has no service or replacement needs that may affect the reliable long-term performance of the probe. Maintenance-free, with no calibration or adjustment required after installation, the device fits into a variety of transformer valves and can be installed and ready to use within minutes.

Maintenance engineer Mikko Piironen from Vantaa Energy Electricity Networks, says: "With Vaisala's MHT410 transmitter we have an altogether more practical and reliable means of monitoring transformer performance. It allows us to optimise the technical life cycle of our transformers and react to potential faults in the very early phase of their development - avoiding costly interruptions to production. The reliability and long-lasting nature of the MHT410's technology make it a key part of our long-term maintenance strategy, helping to extend the lifetimes of our transformers."
