Home - Residential & Distribution - Dry Type Transformers What is the normal life expectancy of a transformer? When a transformer is operated under ANSI/IEEE basic loading conditions (ANSI C57.96), its normal life expectancy is 20 years. The ANSI/IEEE basic loading conditions are: A. The transformer is continuously loaded at rated kVA and rated ...
