What are the signs of a faulty AVR in a generator?
1 - Unstable generator engine speed.
2 - Current overload.
3 - Power surge.
4 - Short circuit.
5 - Age.
What causes an AVR to fail?
It was concluded that the cause of AVR damage was due to the generator driving motor which experienced a decrease in performance so that when subjected to electric load the engine rotation experienced instability which caused voltage fluctuations where this caused the AVR to work abnormally resulting in AVR damage.
