The function of the Potier triangle is to separate

  • The function of the Potier triangle is to separate armature leakage reactance and armature reaction m.m.f.
  • The Potier triangle is a graphical representation of the stator impedance and is constructed by drawing a right-angled triangle.
  • The hypotenuse of the triangle represents the stator impedance, the base represents the armature leakage reactance, and the perpendicular represents the armature reaction m.m.f.
  • The armature reaction m.m.f. is proportional to the armature current, and the armature leakage reactance is proportional to the frequency.
  • By measuring the stator impedance, the frequency, and the armature current, the armature leakage reactance and armature reaction m.m.f. can be separated from the stator impedance using the Potier triangle.
  • The function of the Potier triangle is, therefore, to separate the armature leakage reactance and armature reaction m.m.f. from the stator impedance of the synchronous machine, which helps in the analysis and design of the machine.
