a 3 phase system is an arrangement of three winding
producing 3 single phase voltages of the same magnitude and
frequency but displaced 120 degree electrical from one
another the 3 winding are connected in such a way that 3
voltages act simultaneously in the circuit,each supplying
power at different intervals of time to a comman load.
