Electrical Engineering ⇒ Topic : Advantages and Disadvantages of Phase advancers

Advantages:

• Since the ampere turns are supplied at all slip frequencies, the lagging kVA drawn by the motors are reduced considerably.
• Phase advancers can be used conveniently where the usage of synchronous motors is not possible.

Disadvantage:

• Phase  advancers are not economical for motors below 200 H.P.
