Phase Sequence Simulation
Run DC Shunt motor and check the direction of rotation of motor. Now switch off the DC supply and give three phase
supply to Synchronous machine from Grid supply and run as motor. Again Check the direction of rotation. If both rotations are same
means Phase Sequence is Same otherwise the Phase Sequence is Opposite. In case of Oppositet Phase Sequence change anyy two phases of Synchronous machine.
