Abstract :
The present paper is devoted to evaluation of transformers ageing. In this work 100 set transformers have been selected in order to take samples from transformer´s oil. By direct measuring of deterioration of paper insulation (degree of de-polymerization) and deterioration by-products in oil, insulating papers condition have been studied. Transformer ageing has simulated with an appropriate model based on dissolved gas and furan content in order to evaluation of aging.
