Over the last decade dibenzyl-disulphide (DBDS) was found to be present in many mineral insulating oils. This sulfur compound tends to react with the copper of the windings, forming harmful by-products (Cu2S). Different techniques to overcome the problem such as metal deactivation, oil change and chemical treatment, have been applied. The long term effectiveness of these techniques is examined and compared.

Abstract
Over the last decade dibenzyl-disulphide (DBDS) was found to be present in many mineral insulating oils. This sulfur compound tends to react with the copper of the windings, forming harmful by-products (Cu2S). Different techniques to overcome the problem such as metal deactivation, oil change and chemical treatment, have been applied. The long term effectiveness of these techniques is examined and compared.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
