Transformers are equipment that work in increasing power, balancing voltage in the grid, and/or providing electromagnetic insulation, among other essential functions in power generation and distribution. To ensure that this product meets all system needs, it is important to opt for approved options from the main transformer manufacturers in Brazil. 

Approved Transformers

Before understanding who these companies are, it's important to understand that the homologation of a transformer consists of proving that it complies with the technical standards stipulated by ABNT and ANEEL (Agência Nacional de Energia Elétrica) norms. To obtain this seal, products undergo various checks regarding the equipment's safety, effectiveness, durability, operation, and quality.
