What is the role of dibenzyl disulfide in transformer oil?

The role of dibenzyl disulfide in transformer oil is to enhance the oil’s performance as an insulating and cooling medium. It acts as an antioxidant, preventing the oxidation of transformer oil, which can lead to the formation of sludge and degradation of the oil’s properties. By stabilizing the oil, dibenzyl disulfide helps maintain the efficiency and longevity of power transformers, ensuring reliable operation under various conditions.
