The steam passes into a turbine which consists of narrow blades rightly mounted on a shaft. The blades are moved by the flow of steam and rotate the shaft at a high speed. Almost like the action of wind turning a windmill. After passing through the turbine steam enters a condenser where it is condensed into water and pump back to the boiler for heating and to repeat the cycle.
The electricity generated in the stator is then raised to a high voltage so that it can be more economically transmitted to wider area. Electricity needs a medium to flow in and this normally occurs in conducting cable laid underground or through overhead wire.
At the substation transformers with high voltage and low voltage windings step down the voltage to a level suitable for use in homes, industries, hotels and buildings
