PCB in transformer oil refers to **Polychlorinated Biphenyls**, a group of synthetic organic chemicals that were once commonly used as **insulating fluids** in transformers and other electrical equipment due to their **non-flammability, chemical stability, and insulating properties**.
### Why are PCBs a concern?
- **Toxicity**: PCBs are **toxic** and can cause serious health effects, including cancer and damage to the immune, reproductive, nervous, and endocrine systems.
- **Environmental persistence**: PCBs **do not easily break down** in the environment and can accumulate in the food chain.
- **Banned substances**: Most countries banned the production and use of PCBs starting in the late 1970s to 1980s, but older transformers may still contain PCB-contaminated oil.
### Testing and Disposal:
- Transformer oil is tested for PCB content using methods like **gas chromatography**.
- If PCBs are detected above regulatory limits (often 50 ppm), the oil and the equipment must be **handled and disposed of** according to hazardous waste regulations.
