Transformer
A transformer is an essential electrical device that changes voltage levels in electrical systems. Think of it like a converter that can take high voltage electricity and make it safer and more usable for homes and businesses, or the other way around. Electricians and electrical technicians work with transformers in various settings, from small indoor units that power office buildings to large outdoor ones that serve entire neighborhoods. It's a fundamental component in electrical distribution systems, and understanding how to install, maintain, and troubleshoot transformers is a key skill in the electrical trade.
