siemens so2 leak rate for transformers

A transformer's life is determined by the health of the insulation system. If one tiny piece of the insulation in a critical location fails, electrically or mechanically, the transformer is potentially doomed. The estimated life of a transformer is calculated to be approx. 20.5 years (per IEEE C.57.91) minimum when operated as follows:
