Fundamentals of Electric Power Generation

 · Generation of electric power is by a rotating magnetic field within static windings. Hence the electrically energized rotor with its magnetic poles rotates inside the stator where the electric current is generated at high voltage. This is subsequently stepped up to an even higher voltage by a transformer before long distance transmission.
