RESIDUAL LIFE EXTENSION OF AGED TRANSFORMERS IN ALUMINIUM SMELTERS

摘要

The modern world is increasingly dependent on electricity for economic prosperity. Without doubt the single most important piece of equipment in electrical networks in Aluminium Smelters is the Power transformer. However the average age of transformers around the world is increasing rapidly with transformer failures rising exponentially, and to replace all of the aged power transformers at risk would be prohibitively expensive. This paper focuses on the extension of residual life of these aged transformers through ONLINE RECLAMATION of oil a process through which the parameters of the oil are improved better than the new oil (Specified in IS 335) thereby life extension.
