Damper bars in case of salient pole rotors of hydro-alternators are usually inserted in pole faces to
  • a)
    strengthen the excitation current of the poles.
  • b)
    damp out the rotor oscillations during transient state owing to sudden change in load conditions.
  • c)
    help improve the power factor of load.
  • d)
    reduce the no-load current when load is thrown-off.

Damper bars in case of salient pole rotors of hydro alternators are usually inserted in pole faces to damp out the rotor oscillations during transient state owing to sudden change in load conditions.
The damper winding comes into play only during rotor hunting, when rotor speed departs from synchronous speed.
