Research of Insulation Ageing on Transformer Models

Research of power transformer insulation ageing on transformer models is described. Results of physical, chemical and electrical diagnostic methods on model equipped with open breathing system and on model with closed breathing system are presented. The rate of insulating system ageing in model with open breathing system was 2.5 times faster than in the case of closed breathing system. The monitoring methodology of aging of transformers in service is recommended.
