Many power stations contain one or more generators, rotating machines that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a conductor creates an electric current. 8 kV to suit the size of the unit and primary distribution system voltage. Generators in this size range will be offered by the manufacturer in accordance with its design, and it would be difficult and. . In power plants, mechanical energy is primarily converted into electrical energy, which powers our homes and industries. The journey begins with mechanical energy, often sourced from steam turbines, gas turbines, or hydro turbines.
