PCBs, have been widely used worldwide for about 50 years as insulation in transformers and other electrical equipment (1927, first industrial application by Swan USA).
The lack of reliable, early studies allowed its application on a very large scale, until the dramatic events of the 1970s and 1980s led to the "ban".
The use of PCBs has been restricted for years and banned for use in new transformers by IARC*, the international agency for cancer research, a United Nations agency. The IARC changed the classification of PCB agents from Group 2A to Group 1. This means that PCBs, previously considered "possibly carcinogenic", are now among agents that are "carcinogenic to humans".
Nevertheless, a large number of PCB-contaminated transformers are still operating. It is a legal obligation for industry and power plants to detect the presence of PCBs in transformer oil. Therefore, there is a need for complete information regarding the new direction of the correct PCBs management policy in electrical transformers and capacitors in Indonesia.
This is discussed in a free zoom webinar with the title "New Directions for PCBs Management Policy on Electrical Transformers and Capacitors in Indonesia" on June 23, 2021 pk. 09.00-12.00 organized by PT Hyprowira Adhitama. The speakers for the webinar : Ir. Yun Insiani, MSc. (Pejabat Fungsional Pengendali Dampak Lingkungan Ahli Utama) PSLB3 KLHK, Rio Deswandi (UNIDO), Prof. Kim Jong Guk (Chonbuk University) and Djunaidi Chaidir (Hyprowira).
