Why Dissolved Gas Analysis
Dissolved Gas Analysis (DGA) is a crucial monitoring method for identifying emerging faults in transformer main tanks and related oil-filled equipment. This includes early signs of deterioration for critical faults like partial discharge, overheating, and arcing. While DGA can be performed offline by sampling oil and analyzing it for defects, information about progressive failures before they occur cannot be determined.
By utilizing substantial historical laboratory data, DGA condition monitoring solutions enable precise fault detection and predictive capabilities through online systems. This technique is therefore gaining importance due to the aging global transformer infrastructure, empowering businesses with real-time data, preventing costly downtime and extending transformer lifespan.
Why Rugged Monitoring-
Rugged monitoring’s Dissolved Gas Analysis (DGA) is indispensable on oil filled transformers because these critical assets often operate in harsh environments, demanding equipment built to withstand extreme conditions for continuous and accurate data acquisition. This reliability ensures the early detection of fault-indicating dissolved gases, enabling timely preventive maintenance and minimizing the risk of costly failures, downtime, and safety hazards. Rugged online DGA systems facilitate real-time condition-based maintenance and seamless integration with remote monitoring platforms, ultimately optimizing asset management and extending the lifespan of these vital components.
By sampling and examining the insulating oil of transformers, ratios of specific gas concentrations, their generation rates, and total combustible gases are often used as the attributes for classification by diverse DGA approaches. Temperature measurements are used and can even be incorporated into certain key gases.
