Dissolved gas analysis: addressing the challenges of collecting samples
BY DONAL SKELLY, GE’s Digital Energy business
Dissolved gas analysis (DGA) is a technique for identifying and quantifying the gas formed in oil-filled electrical equipment because of either the natural aging of oil and paper or accelerated aging due to a fault. The quantity and constituents of the gas generated by aging or a fault differ dramatically, but both are important to utility managers who want...

The importance of risk assessment and the role of Reliability-based DGA
By Chuck Hoeppner, Delta-X Research It’s often said that you can’t manage what you can’t measure. But how does one manage risk in the mission-critical, 24x7 world of energy utilities? It’s a challenging undertaking, anticipating future demands and ensuring the reliability...

Advancements in Dissolved Gas Analysis: CO/CO2 Ratio
For DGA interpretation, faults identified using hydrocarbon gases are considered more serious if they appear to affect paper insulation. That is made explicit in CIGRE technical brochure 771[1]. Production of hydrocarbon gases from the oil by electrical or thermal stress does not significantly...
