Fire detection for oil filled transformers - NFPA (fire , malta transformer tank fire volume

I am not sure about the reason for a heat/ smoke detector to cover an oil filled transformer. The oil is normally a non combustible (under definition of NFPA) product and transformers under many circumstances blow up at which point smoke detectors would be meaningless.

Carl, in general transformer bunding is a good idea, but can be a costly exercise for existing installations. Factors to consider are: the cost and lead time of the transformer, its impact on production, whether an oil fire would expose adjacent transformers or buildings and the type of oil used (mineral oil, natural or synthetic esters).
