The following notes should be read in conjunction with the relevant oil testing specifications. Causes of bad oil transformers and switchgear oil may be rendered unsuitable for further use due to four main reasons:- 1. Low dielectric strength. 2. High acidity. 3. High sludge content. 4. Excessive fr...
