Vaisala's real-time online DGA monitors help mitigate the risks and safeguard the power industry's critical assets.
Utilities and industrial clients can now safely increase equipment performance, prolong lifespans, plan for timely maintenance, and prevent unexpected outages.
Dissolved gases appearing in transformer oil indicate a fault, while the rate of change in gas concentrations is used to determine the severity of the fault.
A multi-gas DGA monitor, like the Optimus DGA monitor, is your best choice for critical transformers, as it provides a comprehensive understanding of the transformer's condition. On the other hand, a single-gas monitor, such as the MHT410, can be used as a simple early warning indicator.
Total gas pressure is a groundbreaking method for detecting air leaks into your transformer. It's a robust, reliable, and intuitive method to ensure your transformer is still sealed against ambient air and its oxygen.
Oxygen will prematurely age and weaken the paper in your transformer's windings, potentially shortening your transformer's operational life by years. Total gas pressure is the answer. And comes as standard in the Vaisala Optimus™️ OPT100 online DGA monitor.

In four episodes, you'll get a deep dive into both the science and practice of moisture in oil and measuring it, culminating in a two Expert Q&A sessions with your insights & questions answered by the experts.
Infrared technologies, whether PAS or NDIR, are a great option for DGA monitoring. Infrared also makes it possible to create a maintenance-free DGA monitor that does not need any recalibration — if you can solve the challenge of oil aging.
The following case study explores the detection of severe faults and the overall monitoring process and procedure during an old transformer's final months in service - it's end-of-life (EOL).
Ever-increasing efficiency targets concern all industries and their assets. Power transformers are no different. Maximizing and extending their lifetime is all about meeting this challenge.
