Ensure Transformer “Health” with Online DGA Monitoring

Online Dissolved Gas Analysis (DGA) monitoring plays a critical role in ensuring reliable transformer operation and enabling effective asset replacement planning. But how can you ensure that DGA data remains accurate and trustworthy, especially after years of continuous operation?

Qualitrol delivers the solution with advanced Gas Chromatography (GC) technology.

Key Advantages of Qualitrol’s GC Technology

• Lifetime Accuracy: The greatest advantage of a GC-based system is its ability to perform automatic calibration at regular intervals. Every few days, the analyzer automatically verifies its measurements against a certified reference gas, ensuring that the sensors continue to provide the highest level of accuracy.

• Continuous Data Reliability: Regular automatic calibration eliminates the risk of measurement drift over time, allowing utilities and asset managers to make informed decisions based on accurate and dependable DGA data.

• Superior to Alternative Technologies: Infrared (IR)-based systems often require complex laboratory recalibration procedures or periodic sensor replacement (for example, every five years), creating periods where calibration status and measurement accuracy may be uncertain. Qualitrol’s GC technology overcomes these limitations by maintaining continuous measurement integrity through automated calibration.

Inaccurate DGA data can lead to misdiagnosis, incorrect maintenance decisions, and potentially significant risks to transformer reliability. Choose the solution that delivers lifetime measurement accuracy with Qualitrol’s Gas Chromatography technology.
