Automatic Voltage Regulator (AVR)

An Automatic Voltage Regulator (AVR) is a device that automatically maintains a generator's output voltage within a specific range, ensuring steady power supply. It continuously monitors the voltage level and adjusts the excitation current to the generator's rotor accordingly. This regulation prevents voltage fluctuations caused by changing load demands or generator conditions, protecting connected equipment and improving system reliability. Essentially, the AVR acts as a smart control system that keeps the electrical output stable, making sure the power you receive remains consistent and safe for your devices.
