The power industry is in many ways the backbone of modern society — no power, no connections. And in today’s world, not being connected is unthinkable even for the briefest intervals. We know it, you know it.
The industry faces multiple challenges. Running equipment that’s coming to the end of its designed operational lifespan. The impact of overload situations. An increasing number of network challenges. Vaisala has a strong portfolio of real-time online measurement transmitters for utilities that want to mitigate these risks and safeguard their critical assets.
Vaisala’s DGA solutions let you safely increase equipment performance and prepare timely maintenance plans to prevent unexpected outages.
Take a deep dive under the covers of the OPT100 and our total gas pressure method, learn all about improved DGA, or go for an in-depth analysis on measuring moisture in oil in our latest four-episode webinar series. All our webinars are free to view, and available to watch at the time most convenient for you on demand.
Learn about breakthrough developments in DGA monitoring and our new method of reliably identifying ambient air ingress into your transformer.
A three episode deep dive into the science and practice of measuring moisture in transformers.
Whether you’re looking to gain a comprehensive view of DGA monitoring or to learn about moisture dynamics in transformers, let our experts guide you.

Our flagship DGA monitor, the Optimus™️ OPT100 is the ultimate choice for your critical transformers.
We have rethought transformer monitoring and DGA. We wanted to reduce sampling to a minimum. To go fully online and enable 24/7, always-on monitoring. So you can see more than a sampling-type spot check could —uncover trends and gassing patterns in your critical equipment.
We didn’t stop there. We did away with gas cylinders, and in fact, all consumables. The end result is truly zero-maintenance monitoring technology.
Transformers across the world employ well over 10.000 Vaisala probes to monitor for moisture.
Why? Because of the uniquely robust HUMICAP® sensor. Proven over 20+ years in service in the harshest environments on Earth — and Mars.
Famous for its outstanding measurement performance. In fact, individual probes have come back to Vaisala for calibration checks after 10 years in service, without any maintenance, and upon calibration their sensors were still within their initial accuracy. That’s robust technology.
A multi-gas DGA monitor, like the Optimus™ OPT100, is your best choice for critical transformers providing a comprehensive understanding of the condition of your transformer. A single-gas monitor like our Moisture, Hydrogen and Temperature Transmitter MHT410, is an unbeatably robust early warning indicator of a fault condition.
• The world’s first DGA monitor requiring no consumables
• Track the seven key fault-gases at all times
• Gain a comprehensive understanding of your transformers’ condition
• Now with total gas pressure — ambient air ingress detection
• Unbeatably robust single-gas monitor
• Early warning indicator of a fault condition in your transformer
• Ultimate connectivity and remote monitoring when coupled with the Indigo520 transmitter.
• Easy to install
• 20+ years proven track record
• The true standard for the whole industry
• Light and robust
