Transformer Insulation Class

While transformers are in operation, waste energy generates heat causing an internal temp rise. The insulation class rating is the highest internal temperature a transformer can withstand. For the nominal life expectancy of the device, it is important to stay within this temperature rating. Insulation class rating is an important deciding factor for Engineers for efficiency and life expectancy.
