The low power factor of an induction motor is due to the fact that its stator winding draws exciting current which lags behind the supply voltage by 90 degree. If the exciting phase advancers turns can be provided from some other A.
This job is accomplished by the phase advancer which phase advancers simply an A. They are also used as filters for harmonic oscillations in networks with predominantly nonsinusoidal loads.
Static phase advancers are used in rectifier conversion devices that have forced triggered phase advancers. The choice of phase advancer type depends on engineering and economic factors, including the nature of the network loads, the rate and range of load changes, and the operating conditions of the network.

The capacitor generally known as static capacitor draws a leading current and partly or completely neutralizes the lagging reactive component of load current.
This raises the power factor of the phase advancers. For three-phase loads, the capacitors can be connected in delta or star.
What are Phase advancers? - Quora
Advantages They require little maintenance as there are no rotating parts They can be easily installed as they are light and require no foundation They can work under ordinary atmospheric conditions Disadvantages They have short service life ranging from 8 to 10 years They are easily damaged if the voltage exceeds the rated value Once the capacitors are damaged, their repair is uneconomical Synchronous condenser A synchronous motor takes a leading current when over-excited and, therefore, behaves as a capacitor.
An over-excited synchronous motor running on no load is known as phase advancers condenser.
When such a machine is connected in parallel with the supply, it takes a leading current which partly neutralizes phase advancers lagging reactive component of the load.
Thus the power factor is improved.
