Gestión de los transformadores eléctricos con bifenilos policlorados de la Empresa Centrosur

Abstract

For the transportation and distribution of electric energy it is use an equipment called transformers, which have added a chemical substance called Polychlorinated Biphenyls (PCBs), that will improve the stability of the oils that are used as refrigerants.

Since 1980 the use of this substance is prohibited for their polluting action and the serious problems caused to the environment and human health; however contaminated equipment with this chemical are in our country, some in storage and other running. The energy company Regional CENTROSUR owns such equipment, so comes the need to develop a proposal for a system to manage the electrical transformers with polychlorinated biphenyls; this system provides parameters for quality, safety and environment; as well as a technical and economic analysis is performed based on the different treatments for the decontamination and disposal of PCBs.

Additionally, this document provides a proposal of MDL project based on the change of the contaminated transformers for transformers free of PCBs and more efficient.
