PCBs Cross-Contamination in Transformer Oil: Mitigation for Environmental and Health Protection
Keywords:
polychlorinated biphenyls, pcb management, cross-contamination, transformer oil, environmental protection, hazardous waste, sustainable managementAbstract
Polychlorinated Biphenyls (PCBs) are hazardous compounds that have been widely utilized in transformer oil for insulation purposes. Due to their persistent, toxic, and non-biodegradable nature, improper handling of PCBs can result in contamination of surrounding electrical equipment, posing serious risks to the environment and human health. This study aims to evaluate current PCB management practices and develop effective methods to prevent cross-contamination. The methodology involves electrical testing on active (online) transformers and surface wipe sampling on offline units stored in warehouses. The findings are expected to facilitate early detection of contamination, improve management efficiency, and support the implementation of preventive protocols. The results underscore the urgency of robust PCB management to mitigate environmental degradation and protect public health through safe handling, testing, and storage strategies.
