Transformer End Of Life at Archie Gallop blog

Transformer End Of Life. Tepco decommissioned 20 transformers with a service life of between 30 years and 50 years to evaluate the level of deterioration as a result of aging. Therefore, the end of transformer paper life is the end of the transformer life. The average life span of general purpose dry type transformers are more than 25 years. If an air cooled dry type transformer operated in dust free, well ventilated avoiding direct hit, dust, wet and humidity with rated parameters, it may last more than 35 years even 50+ years. To estimate the remaining life of the transformer (cellulose insulation), a chemical indicator called the degree of polymerization (dp) is used. It is generally the insulation that determines the life expectancy of a transformer, assuming that no catastrophic failures occur due to external factors. However, the oil condition in transformers plays a significant role in the ageing process of cellulose. Bsen60076 part 7, clause 6.4, table 3 states that standard transformer insulation is designed for 180000 hours of service (20.5 years) when working at full load and 98°c hot spot.
