Sinchronous motor is used to improve power factors.
Most of our equipments & electrical machinary are inductive
load i.e. in industries,institutions,large offices &
commercial buidlings are having large electrical system .
To improve the cosine angele between voltage & current we
are puting capacitor bank & Sychronous motor.
Sub-stations are having above power factor improvement
