the acid value, surface tension, ph value of aqueous extract and oil color were measured in noninhibited transformer oils aged by microbial and thermooxidation effects. it is found that considerable microbial degradation of transformer oil occurs when free water is present in the oil. degradation is accelerated by the biological decomposition of moistened crepe-paper and cotton-tape wrappings immersed in the transformer oil.
