Phase Advancer and its Types:
A phase advancer is a device that helps in improving the power factor of an induction motor. It is used to provide a leading current to the stator winding of the motor, which helps in compensating the lagging current in the rotor winding. The following are the types of phase advancer:
1. Capacitor Phase Advancer: It is used to improve the power factor of the induction motor by connecting a capacitor in series with the auxiliary winding of the motor.
2. Resistance Phase Advancer: It is used to improve the power factor of the induction motor by connecting a resistor in series with the auxiliary winding of the motor.
3. Synchronous Motor Phase Advancer: It is used to improve the power factor of the induction motor by connecting a synchronous motor in the rotor circuit of the induction motor.
Role of Synchronous Motor in Phase Advancing:
A synchronous motor operating at leading power factor can be used as a phase advancer. When a synchronous motor is connected in the rotor circuit of an induction motor, it helps in improving the power factor of the induction motor. The synchronous motor operates at a leading power factor, which cancels out the lagging power factor of the induction motor. As a result, the overall power factor of the system improves.
Advantages of Using Synchronous Motor as Phase Advancer:
1. The synchronous motor phase advancer is more efficient than the capacitor or resistance phase advancer.
2. The synchronous motor can provide a leading current to the induction motor, which helps in improving the power factor of the system.
3. The synchronous motor phase advancer can be used for a wide range of motor sizes and ratings.
Conclusion:
In conclusion, a synchronous motor operating at leading power factor can be used as a phase advancer to improve the power factor of an induction motor. The synchronous motor provides a leading current to the stator winding of the motor, which compensates for the lagging current in the rotor winding. This results in an overall improvement in the power factor of the system.
