AVR is
An automatic voltage regulator (AVR) is a solid state electronic device for automatically maintaining generator output terminal voltage at a set value. It will try and do this as the generator load or operating temperature changes. The AVR is part of the alternators excitation system.
How does an AVR work?
It controls output by sensing the voltage from the generator terminals and comparing it to a stable reference. The error signal is then used to adjust the field current by increasing or decreasing the current flow to an exciter stator, which in turn will lead to a lower or higher voltage at the main stator terminals.
It has 4 wires .. 2 wires input AC 220 other 2 wires output connected to exiter alternator. Thank you for correcting 🙏
