Variable-speed air-forced cooler technology

Abstract

Advanced air coolers are able to cool transformer oil more efficiently than older systems. Replacement or expansion of cooling plants by a new solution can lead to reduction of oil temperatures by several degrees and have a positive influence on the service lifetimes of oil and therefore transformers. Or, conversely, better coolers can – at the same oil temperatures – enhance the maximum performance of a transformer or allow it to operate at a higher average load. The upgrade or expansion of a cooling system in some cases can eliminate the need for immediate investment in a new transformer, or extend the life cycle of existing transformers.
