Abstract
Power transformers are the most important facilities in the substation of electrical power, yet they do not have the efficient operating life characteristics which are the important elements of repairing and maintenance in regional conditions. This paper describes the statistical analysis of operating conditions and troubles on transformers for the operating life assessment using Statistical Analysis System programs, Hazard method and Weibull distributions. We analyze transformers in several methods, and compares correlation relationship of operating life and troubles. Therefore, this study will be the useful basic operating life prediction technique of power transformers in the future.
