Polychlorinated biphenyls (PCBs) in transformer oil are chemical compounds that were used for their stability and insulating properties. However, PCBs are highly toxic and persistent in the environment, leading to their ban or strict regulation in many countries. Transformers containing PCB oils are being phased out due to these risks.
