Dissolved Gas Analysis in Transformer Oil· Dissolved Gas Analysis in Transformer Oil 1. In substation, Transformer is the most efficient and costly equipment. So in order to protect from faults, Transformer oil testing is required. The transformer's fluid not only serves as a heat transfer medium, it also a part of transformer's insulation system. It is therefore prudent to periodically perform tests on the oil to determine whether ...
