What is DBPC in transformer oil?

DBPC, or dibenzyl phthalate, is an additive used in transformer oil to enhance its dielectric properties and thermal stability. It helps improve the oil’s performance by increasing its resistance to oxidation and degradation, thereby extending the lifespan of the transformer. Additionally, DBPC contributes to better insulation characteristics, which is crucial for maintaining the efficiency and reliability of power transformers in electrical systems.
