EVALUATION OF POWER TRANSFORMER INSULATION RESIDUAL LIFE BASED ON ITS INDIVIDUAL LIFE CYCLE CHARACTERISTICS

Abstract

Analysis reveals that all phases of a power transformer life cycle have a significant effect on the isolation resource. The paper introduces a technique for evaluating residual life of power transformer insulation via simulation of predicted results of external factor actions on the transformer insulation condition.
