Abstracts
Gases dissolved in insulating liquids are generated by thermal deterioration of the insulating liquid or they are introduced by contact with a gaseous environment (air, for example). Gases can also be formed by normal ageing processes of the liquid or catalytic interactions with metals or paints. The analysis of these dissolved gases is called DGA. Electrical equipment suitable for DGA are power transformers, industrial and special transformers, instrument transformers, bushings, cables and switching equipment. DGA for transformers has been established more than 40 years ago and since then was continuously refined according to the proceeding technical development of liquid-filled transformers.
