Abstract

Transformers are key assets in a power plant. This article explores the use of mapping transformer populations to quantify the operational and economic costs due to various risk factors, including design, external, and accelerated aging risks.
Generation, start-up, and auxiliary transformers are typically designed for specific functions within an operating block in a power plant. The planning, manufacturing, and installation of custom-designed power transformers can take many years to complete.
Once in operation, the premature failure of these critical assets before
their expected End of Life (EOL) can be devastating to the electric utility or industrial company owner. The mapping process aids in the proactive
identification of those transformers that may create the most economical and performance risk. The process helps to identify remediation, conservation, and conditioning actions that ensure that these critical assets function throughout their planned lifetime.
