Moisture, Hydrogen and Temperature Transmitter MHT410

for Power Transformer Online Monitoring

Is your power transmission and distribution secured? Continuously monitoring hydrogen and moisture levels with an in-situ probe is the first step in extending the life of a transformer through implementation of predictive maintenance practices leading to lower total cost of ownership.

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. The 5-year warranty proves outstanding reliability of this single gas monitor.

Key Benefits

Measures directly from oil

No need of pumps, membranes etc. Transmitter MHT410 measures directly from representative transformer oil giving both reliable hydrogen trend as well as fast moisture data.

Fast measurement

Monitors health of the transformer in real time giving both reliable hydrogen trend as well as fast moisture data.

Unique probe design, robust and easy to install

Isolated inputs and outputs, EMC tolerant device with IP66 metal housing. Supplied with standard DNP3.0 and MODBUS communication protocols, thus allowing easy deployment within existing communications and SCADA networks. The MHT410 also includes three analog outputs for SCADA interface.

Continuous monitoring gives full visibility

“It is completely different to follow the situation continuously than to take samples every now and then. After all, electricity networks can have quite exceptional switching situations – a transformer can have very high momentary loads and at other times be used only lightly.”

Graphic display with the Indigo 520 Transmitter

MHT410 is also compatible with the Indigo 500 series transmitters. While MHT410 helps you prevent power outages and detect possible faults beforehand, Indigo 520 is a great addition with its local graphical display. It helps you to identify data trends at the site, as well as power the MHT410 with a single-wire solution.
