Automatic Voltage Stabilizer (AVS) play a crucial role in voltage regulation within electrical power systems. Here are the key functions and roles they perform: 1. Voltage Stability: AVS maintain a stable output voltage from generators, compensating for fluctuations caused by changes in load or input voltage. 2. Generator Protection:They protect generators from damage due to over-voltage or under-voltage conditions by ensuring that the voltage remains within safe operating limits. 3. Improved Ef
