Transformer Bushing Failure Signs

Working of Conservator Tank. When volume of transformer insulating oil increases due to load and ambient temperature, the vacant space above the oil level inside the conservator is partially occupied by the expanded oil. Consequently, corresponding quantity of air of that space is pushed away through breather. On other hand, when load of pakistan transformer tank fire volumeTransformer Foundation - Oil Containment Area Sizing pakistan transformer tank fire volumeMar 24, 2011I am working on a design of a transformer foundation. Transformer contains 1050Gal of oil. That is quite a bit of oil, that would require 146 cu. ft. of containment volume around the transformer pedestal, if I add crushed stone into the pit, it will quadruple the volume. I have an option of building an underground containment tank with a sump pump.Transformer Foundation - Oil Containment Area Sizing pakistan transformer tank fire volumeMar 24, 2011I am working on a design of a transformer foundation.

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).CONSTRUCTION STANDARDS STANDARD DRAWINGS52. 31 2050 Rev.
