Load characteristics of DC shunt generator



  •     Internal and external characteristics are called as load characteristics.
  •     These are obtained by running a generator on load at constant speed and keeping the setting of the field regulator fixed.
  •     If the variation of terminal voltage with the variation of load currents is plotted we get the external characteristics.
  •     To this external characteristic, if voltage drop in the armature circuit is added we get the internal characteristics of the dc shunt generator, which gives the variation of induced emf. on load with the variation of armature current.
