Abstract

With the need to show increased return an assets, engineers are faced with the dichotomy of reducing capital and maintenance expenditure whilst attempting to meet more demanding supply availability criteria. Transformers are vital components within power distribution systems and it would be advantageous if their service life could be extended, without detracting from reliability. This paper examines how continuous moisture removal systems, utilising ceramic molecular sponge materials, affects service life, maintenance and reliability of transformers. Experience of systems operating in 24Seven Utility Services Ltd are reported
