PCB levels in transformer oil are crucial for ensuring the safety and compliance of electrical equipment. Polychlorinated biphenyls (PCBs) were commonly used in transformer oils due to their excellent insulating and heat transfer properties. However, due to their toxicity and environmental impact, regulations have been established to limit PCB concentrations in transformer oil. Generally, PCBs are measured in parts per million (ppm), with levels above 50 ppm categorized as hazardous, leading to strict handling and disposal requirements. It’s important for operators to regularly monitor PCB levels in transformer oil to prevent contamination, ensure regulatory compliance, and maintain the integrity and longevity of the transformer system. Regular testing and appropriate oil regeneration or cleansing can mitigate PCB issues, safeguarding both the equipment and the environment.
