Cut the guesswork – DGA reimagined

Electricity is a backbone of modern society – no power, no connections. In today's world, being connected is unthinkable even for the briefest intervals.

Vaisala's real-time online measurement transmitters are the choice of utilities & plants that want to safeguard critical assets, prevent unexpected outages, increase performance, and prepare timely maintenance plans.

Advanced DGA – Optimus™ OPT100

Our flagship DGA monitor is the ultimate choice for critical power transformers.

We reduced sampling to a minimum. So you can go fully online and enable 24/7, always-on monitoring, see more than a sampling-type spot check could, and uncover trends and gassing patterns. We also did away with gas cylinders, and all consumables. The end result? True zero-maintenance monitoring.

GET TO KNOW THE OPTIMUS™

Better know better

Transformers across the world employ well over 10.000 Vaisala probes to monitor for moisture. Why? Because of our uniquely robust HUMICAP® sensor. Proven over 20+ years in service in the harshest environments on Earth and Mars.

Individual probes have come back for calibration checks after 10 years in service, without any maintenance, but with their sensors still within their initial accuracy. That's robust technology.

SUPERIOR MOISTURE MEASUREMENT
