Transformers have the single highest value of the equipment installed in substations reaching 60% of the total investment. Asset managers are constantly under pressure to improve the financial and technical performance of transformers, which has pushed utilities to assess the actual condition of their transformers. Condition assessment contributes to achieving the optimal balance between maintenance costs and operating performance and provides asset managers the economic and technical justifications for engineering decisions and capital replacement plans.
