Cut the guesswork — reimagine DGA

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.
