The presence of corrosive sulphur in current insulating oils is discussed and typical winding failures in transformers and shunt reactors, due to the resultant formation of copper sulphide films and particulate matter, are described. Different standard test methods for the detection of corrosive sulphur in oils are compared and ASTM D1275 is shown to be the most sensitive.

Abstract
The presence of corrosive sulphur in current insulating oils is discussed and typical winding failures in transformers and shunt reactors, due to the resultant formation of copper sulphide films and particulate matter, are described. Different standard test methods for the detection of corrosive sulphur in oils are compared and ASTM D1275 is shown to be the most sensitive.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
