Vaisala has shipped first orders for the new, unique in-oil condition monitoring probe that provides critical early warning information to track transformer faults.  Vaisala has shipped the first customer orders for the new Moisture, Hydrogen, and Temperature Transmitter – the MHT410. This device is designed to help power and energy utility companies minimize transformer-related downtime. 

Mitigating risks in power transmission

High voltage transformers are critical in the generation and transmission of electricity. Any transformer downtime will prevent the export of electricity, leading to substantial financial losses and energy shortfalls for national grids. Lead times for transformer repairs and replacements can be several months.

Long-term maintenance strategy with MHT410

Vantaa Energy Electricity Networks Ltd is one of the beta customers who have tested the transmitter for months. Maintenance Engineer Mikko Piironen says: “Vaisala’s MHT410 allows us to optimize 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 lifetimes of our transformers.”

Designed for reliability

Vaisala’s MHT410 benefits from a unique adjustable probe design that’s installed in the transformer oil. This places its sensors in direct contact with representative oil in the transformer providing measurements and data with unparalleled accuracy.

The MHT410 has no complex pumps, hoses, batteries and other consumable parts. It 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 MHT410 fits into a variety of transformer valves and can be installed and is ready to use within minutes – as experienced by our clients.

Power Transformer in Alajärvi, Finland

The Vaisala Moisture, Hydrogen and Temperature Transmitter MHT410 for Transformer Oil measures directly from representative transformer oil giving both reliable hydrogen trend as well as fast moisture data. MHT410 is built to last and does not have wearing parts such as membrane, pumps, hoses or batteries – maintenance free operation. Unlike conventional hydrogen and moisture meters of power transformers, the Vaisala MHT410 is easy to install and mount to an operational transformer quickly.
