Abstract

Although there are still uncertainties regarding the extent to which climate change may be occurring, some approximations and reasonable assumptions can be made relating to daily high and low temperatures. Further, urbanization may impact ambient temperature. These temperature models may be used with standardized methods to estimate the loss of life of oil-immersed power distribution transformers. In this way, the impact of increased ambient temperatures on distribution transformer loss of life may be preliminarily assessed. Results of standardized engineering studies for illustrative cases are shown in this paper.
