TRANSFORMER FLUID: A POWERFUL TOOL FOR THE LIFE MANAGEMENT OF AN AGING TRANSFORMER POPULATION

摘要

It has been estimated that transformer fluids contain about 70% of the diagnostic information available for transformers. The challenge is to access and use this information effectively. Historically, testing programs have been developed that evaluate separate facets of the transformer condition. This paper considers the dynamics of transformer components considered together as a system leading to a comprehensive testing program for determining transformer condition. Particularly with the changing needs of the electric power industry, optimized testing and diagnostic protocols will be fundamental to transformer life management in the future.
