This project is in Northern Emirates. The project is about Provision of 33/11kV Substation and Cable Works. The electricity is transmitted at very high voltages and low currents to reduce the heat, eddy currents, and other transmission losses. The substations are where the voltages are increased to high values by using step up transformers, and after the transmission, they are again stepped down for distribution. The project substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. ... The word substation comes from the days before the distribution system became a grid.
