what are power angles in electricity
Power angle is also same in context of synchronous machines but it is more generic â also used in power transmission line. To explain what they are: Load angle (or Torque angle): For a synchronous generator, the magnetic field rotates at synchronous speed and the rotating magnetic field is created in the stator. But the fact is that Load angle or power angle is the angle between terminal voltage and excitation voltage. Torque angle is the angle between excitation field mmf and resultant air gap mmf....in a synchronous generator. The load angle and torque angles differ due to the presence of armature leakage emf.
