What is AVR and tell its principle and working ?

  • AVR is Automatic Voltage Regulator which is nothing but Stabilizer.
  • In AVR their is motor which is connected to the auto transformer with buck and boost transformer, as the voltage changes the sensing microprocessor based card will sense and compare with the set value and give command to the buck/boost transformer and motor rotate and set the required voltage.
  • AVR support the control system in three main ways,
    • Sense volts that moving to the main armature.
    • Supply current to exciter field in the generator.
    • AVR, will continue to function until generator produce required output.
