WebThe primary coil is connected to an AC supply. An alternating current passes through a primary coil wrapped around a soft iron core. The changing current produces a changing magnetic field. This induces an alternating voltage in the secondary coil. This induces an alternating current (AC) in the circuit connected to the secondary coil. WebElectric current is generated with a voltage of 25,000 volts. A large substation like this one will increase the voltage to 132,000 or 400,000 volts ready for transmission across long distances. These large substations are also known as 'grid' substations. The high voltage electric current usually leaves the grid substation on overhead lines ...
