What is common regular cause of AVR generator failure?

A common regular cause of AVR (Automatic Voltage Regulator) generator failure is a malfunction in the voltage sensing circuit, which can lead to improper voltage regulation. This may result from issues such as wiring faults, component wear, or environmental factors like moisture and temperature extremes. Additionally, overheating due to overloading or inadequate cooling can also contribute to AVR failure. Regular maintenance and monitoring can help prevent these issues.
