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 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. Maintenance Free Total Cost Savings with the Optimus DGA Online Monitor You get maintenance free monitoring with the Vaisala Optimus™ DGA – no consumables, mechanicals or need for calibration. So when compared with traditional DGA monitors, the Optimus OPT100 DGA monitor gives you real-time monitoring with no false alarms, no maintenance – and no extra lifetime costs. By providing reliable trend data in real time and without false alarms, the Vaisala DGA Monitors helps you detect upstream problems.
