Electric Power Line Grid Transformer Step Down Stock Photo

Electric powerline grid transformer. The transformer step down is shown with blue sky and clouds. Lines that carry higher voltage will need to be stepped down further before entering residential buildings and most businesses. This often happens at another substation or in small transformers somewhere down the line. For example, you will often see a large green box perhaps 6 feet or 1.8 meters on a side near the entrance to a subdivision. It is performing the step-down function for the subdivision.
