Análise de soluções para implementação de redundância operacional em relação aos transformadores da subestação 12 do Centro de Tratamento de Fumos (FTC) da Mozal - Beluluane

Abstract

This study aims to analyze solutions for implementing operational redundancy in the transformers of Substation 12, which supplies power to the Fume Treatment Centers (FTCs) at Mozal, located in the Beluluane Industrial Park. The lack of redundancy directly compromises the continuity of the production process, as failures or maintenance of the transformers may cause interruptions in the FTCs and consequently in the anode baking furnace, affecting production rates and resulting in significant financial losses. The methodology employed includes bibliographic review, field data collection, technical analysis of the equipment, and consultation of specialized catalogs. The results highlight the impacts of the absence of redundancy, present technically viable alternatives, and identify the most suitable solution considering reliability, operational safety, and costs. The recommended proposal ensures greater system availability and contributes to the continuity, efficiency, and stability of anode production.
