Transformers are mainly step-up or step-down. Today let’s talk about step-down transformers. Under this category, there are two types. A three phase and a single phase transformerThe national grid is supplied with three phase from a substation to a transformer through high tension power lines in three or single phase. The transformer steps down that power from 11kV to 415v for three phase low voltage lines or to 240v single phase low voltage power line. #electrical #electrician #wiring #electric
