EVALUATION OF POWER TRANSFORMER INSULATION RESIDUAL LIFE BASED ON ITS INDIVIDUAL LIFE CYCLE CHARACTERISTICS
Journal Title: Електротехніка і Електромеханіка - Year 2014, Vol 0, Issue 3
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.
