What are the technical considerations for pcb in oil transformers?

When considering PCB (polychlorinated biphenyl) in oil transformers, key technical considerations include the environmental impact, regulatory compliance, and the potential for leakage. PCB-containing oils are hazardous, requiring careful handling and disposal. Additionally, the dielectric strength and thermal properties of the transformer oil must be evaluated, as PCB can affect insulation performance. Regular monitoring for PCB levels and implementing containment measures are essential to mitigate risks associated with PCB contamination.
