The armature leakage reactance is a parameter that accounts for that part of the ______ produced by the armature.

  • The armature leakage reactance is a parameter that accounts for that part of the Magnetic flux produced by the armature.
  • The armature leakage reactance is a parameter that represents the opposite of the armature winding to the flow of AC current due to the leakage flux.
  • The leakage flux is the portion of the magnetic flux produced by the stator winding that does not link with the rotor winding, and hence, does not contribute to the generation of the electromotive force (EMF) in the alternator.
  • The armature leakage reactance is a function of the physical dimensions and the geometry of the stator core and winding and is typically expressed in ohms or per unit of the rated voltage or current.
  • The leakage reactance affects the voltage regulation of the alternator and is an important parameter to be considered in the design and analysis of the machine.
  • While the armature leakage reactance does account for the leakage flux produced by the armature, it does not account for the effect of armature reaction, which is the distortion of the main field due to the interaction between the armature current and the main field.
  • The armature reaction can cause significant voltage drop and waveform distortion in the output of the alternator and is another important factor to be considered in the analysis and control of the machine.
