AVR’s applied to three-phase generators most commonly use the same sensing circuit as single phase generators.

A three phase generator maybe set up with either a single or three phase sensing regulator. A single phase generator must be fitted with a regulator that senses single phase. Generator voltage changes with changes in speed of the prime mover (AKA diesel, LPG, or NG Engine)Īs there are various voltages that Generators run at 120v ,240v, 208v, 277v, 480v, 600v AVR’s can be equipped to sense single phase or three phase generator voltages.

Generator voltage drop is caused by generator impedance Generator output voltage can be varied by filed current changes.There is 3 characteristics of the generator that are important to control the voltage of a generator. This drop in generator voltage with increasing load is the reason for using AVR to adjust generator voltage with changes in load. When a generator applies load increases current the voltage drop will occur across the series generator impedance. As no generators today cannot regulate voltage regardless of the load voltage regulators become very necessary. A generator’s impedance causes a charge in generator output voltage when current flows out of the generator.

The generator’s impedance is the resistance to the flow of electrical current. An important part to voltage regulation is generator impedance. To understand Automatic Voltage regulation it is important to understand that is necessary to control voltage of generator for many reasons the most important being safety.

As Tomahawk discusses the importance of automatic voltage regulation or AVR we will focus on voltage basics, digital excitation technology, paralleling of generator sets, and power system stabilizers.Ī majority of the generators Tomahawk will be selling in reference to diesel standby units or portable generators utilizes brushless excited generators.
