Dissolved Gas Analysis (DGA) in Power Transformers Download white paper Gas Monitors for Dissolved Gas Analysis The power industry is currently facing the challenges of safely running equipment coming to the end of its operational lifespan, the impact of overload situations, as well as an increasing number of network faults. To address this situation, Vaisala offers a diverse portfolio of real-time online measurement transmitters for utilities who want to mitigate these risks and safeguard their critical assets. Watch the video TGP Total gas pressure Maximize your power transformer's operational life Total gas pressure is a groundbreaking method for detecting air leaks into your transformer. It's robust, it's reliable, and it's intuitive. And the best part is that it comes as standard in the Vaisala Optimus™️ OPT100 online DGA monitor. Click to learn more Watch the video Maintenance free monitoring with the Vaisala Optimus™ OPT100 DGA Using Vaisala DGA Monitors, moisture-in-oil, hydrogen-in-oil, temperature, dew point, pressure and density meters, utilities can safely increase equipment performance and prepare timely maintenance plans to prevent unexpected outages. A multi-gas DGA monitor, like the Optimus DGA Monitor, is the best choice for your critical transformers providing a comprehensive understanding of the condition of your transformer, whereas a single-gas monitor, Moisture, Hydrogen and Temperature Transmitter MHT410, can be used as a simple early warning indicator of a fault condition.
