Corrosive Sulphur effect in power and distribution transformers failures and treatments

This research has been developed and it has considered a failure mode caused analysis by corrosive Sulphur phenomenon, the problem was solved on 61 power and distribution transformers, and the novel contribution is a recommendation detection, corrective maintenance, different procedures with advantages and disadvantages the reparation and expected remaining life in the transformers, it will prevent an engineering failure on power and distribution transformers, for high and medium voltage.
