Do you need a voltage regulator with a generator?
Without a voltage regulator the voltage out of the generator will be more than just unstable. If you provide a fixed voltage to the field coils, the voltage out of the generator will be entirely dependant on the load you put on it.
Does my generator have AVR?

Simple answer noMoreHi I’m style from generator guru I quite often get asked or AVR is all the same no. Simple answer no they may look the same.
Why AVR is used in generator?
An automatic voltage regulator (AVR) is a device used in generators with the purpose of automatically regulating voltage, which means that it will turn fluctuating voltage levels into constant voltage levels.
Is automatic voltage regulator found at home?
It can be in the main control box of the generator, it can be in the alternators terminal box and it could be (only on very small portable units usually) located under the alternators rear cover.
Are all generator AVR the same?
AVR’s all look remarkable similar – they vary a bit in size and color, but seemingly all have similar features. You can find the AVR you need at the find the AVR support page.
Do brushless generators have AVR?
There are several models of AVRs for brushless generators on the market, such as the GAVR-8, GAVR-12 and larger ones, which don’t use these windings, instead taking all their power from the main 230V output.
What happens is a generator AVR fails?
What happens is a generator AVR fails? If the AVR on your generator fails, then the generator will lose excitation. This loss of excitation will cause the voltage to fall suddenly at the generators and this loss of voltage should cause the generator to shut down on an under-voltage fault.
What does the AVR field mean on a generator?
Designates whether or not the generator is available for automatic voltage regulation (AVR). When the AVR field is checked, the generator will automatically change its reactive power output to maintain the desired terminal voltage within the specified reactive power range.
What is an automatic voltage regulator (AVR)?
An automatic voltage regulator (AVR) is a electronic device for automatically maintaining generator output terminal voltage at a set value under varying load and operating temperature.
What is an AVR and why do you need one?
AVRs can be a good source of protection against these frequent occurrences. AVRs also come with warning signs that will alert you during a power surge. This is called built-in circuit breakers. Similar to transformers, AVRs have a fuse protective device that detects any excessive voltage levels.
How does an AVR work during a power surge?
AVRs also come with warning signs that will alert you during a power surge. This is called built-in circuit breakers. Similar to transformers, AVRs have a fuse protective device that detects any excessive voltage levels. The fuse will blow to signify that a power surge is currently happening.
