Abstract :
In general, the life of distribution transformers is very dependent on the conditions of oil insulation and winding. Some disturbance conditions and the transformer overloading capacity can cause a high-temperature rise and accelerate the decrease in insulation level so that the loss of life of the transformer can be even greater. While the recent population of distribution transformers mostly consist of Copper (Cu) and Aluminum (Al) winding. Based on that fact, this study determine the life time of distribution transformers for both technologies. Life assessment is executed using loss of life analysis due to the disturbance phenomenon called cold load pick up (CLPU) and loading conditions. Using data sample at DK 31 distribution transformers installed at PLN UP3 Cengkareng Jakarta, the loss of life is conducted using CLPU algorithm and IEC 60354 and 60076-7 calculation. The result of study found that the life time of copper winding (CLPU :0,3329116 hour/day &IEC 354:5,17117hour/day ) is longer than aluminium winding transformers (CLPU : 0,4512987hour/day & IEC 354:13,38338hour/day).
