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...
