What Causes Electrical Transformers to Fail? - Corefficientcorefficientsrl.com/causes-electrical-transformers-failAs faults in the insulation develop, further problems accrue, such as moisture absorption in the transformer oil. Dissolved gas analysis should be performed frequently to detect whether the oil is contaminated with gas or moisture. The type and amount of contaminant can help to determine what type of fault has occurred.
