The management of transformers and the insulating fluids they contain presents numerous critical issues (pathologies) that can compromise the efficiency and safety of facilities, productivity, and the environment.
WIKITRANSFO is a resource dedicated to understanding these pathologies and how they can be treated.
Incidents involving explosions and fires, the presence of PCBs and other hazardous substances in the oil, or sulfur-induced corrosion are just some of the challenges Sea Marconi faces daily. Additionally, problems such as oil contamination with water, electrical and thermal failures, and the degradation of insulating papers are further critical aspects that require a specialized approach.
WIKITRANSFO by Sea Marconi has a dual objective: on one hand, to provide new tools for understanding, and on the other hand, to offer targeted solutions ensuring maximum efficiency and operational safety.
