Abstract :
Corrosive sulfur in transformer oil has been identified to cause sudden and unexpected failures of several transformers in recent years. It has been decades since corrosive sulfur has caused such problems. This paper discusses the problems caused by corrosive sulfur, why the problem has resurfaced, new test methods developed to detect corrosive sulfur, and remedies suggested to prevent further destruction.
