State the methods of improving power factor?
Methods of improving power facto?
1.\tBy connecting static capacitors in parallel with the load operating at lagging power factor.
2.\tA synchronous motor takes a leading current when over excited and therefore behaves like a capacitor.
By using phase advancers to improve the power factor of induction motors. It provides exciting ampere turns to the rotor circuit of the motor. By providing more ampere-turns than required, the induction motor can be made to operate on leading power factor like an overexcited synchronous motor.
