Parameters and Applications

HYDROGEN IN OIL

MOISTURE IN OIL

RELATIVE HUMIDITY

DEW POINT

DISSOLVED GAS MONITOR

Power Transformers

Online monitoring of dissolved gases and moisture in power transformers maximizes safe performance, provides early warning of transformer fault situations, and supports planning of timely maintenance that minimizes outages

Ensure correct dew point levels during transformer commissioning and servicing in the field using vacuum dryout. Vaisala’s fixed and portable dew point instruments offer fast response time, enabling quick and reliable verification of specified moisture levels

SF6 Gas Insulated Equipment

Confirm the dew point, pressure, temperature and density in SF6 filled circuit breakers and switchgear with a reliable DPT145 multi-parameter probe.

Turbine Inlet Air

Accurate measurement of inlet air humidity is essential for better turbine control and improved performance. Vaisala's humidity monitoring helps the utility operator optimize the temperature and compression of the inlet air, maximizing output without risking condensation.

Hydrogen Cooled Generators

Achieve best yield by monitoring humidity and temperature of hydrogen cooled generators

Weather & Energy

Utility companies and transmission system operators manage weather impacts daily. Lightning alone accounts for nearly half of transmission system events. In addition, the renewable energy industry uses wind, sun, and water as fuel and needs to assess resources and forecast energy availability to stay competitive. Learn how Vaisala can help you improve your transmission system operations, your development projects, and your renewable energy operations.
