What Are The UVR and AVR Specifications for Diesel Generators?

What is UVR6 AVR?

The Mecc Alte UVR6 automatic voltage regulator was widely used in large Mecc Alte products before they were converted to digital AVRs. This simulated AVR has been used throughout the entire Mecc Alte AC generator series for many years.

What is AVR?

AVR is a generator automatic voltage regulator, which is a solid-state electronic device used to automatically maintain the set voltage at the output end of the generator. It will attempt to do so due to changes in generator load or operating temperature. AVR is a part of the excitation system for AC generators.

Who provides an automatic voltage regulator?

Usually in generator sets, AC generator manufacturers will provide automatic voltage regulators for their AC generators. The largest manufacturer of diesel generators and AC generators is Stanford AVK, Mecc Alte, Recently, Lelesen Ma has been WEG. The supplied model will depend on the AC generator and any accessories installed on it, which may require different automatic voltage regulation. An example of this attachment is the Chief Accountant of the Ministry of Finance or an auxiliary winding.

Where is the AVR located on the generator?

Usually, the generator AVR is located in one of three positions. It can be located inside the main control box of the generator, the junction box of the AC generator, or under the back cover of the AC generator (usually only on very small portable devices).

How does AVR work?

It controls the output generator terminals by detecting the voltage from them and compares them with a stable reference value. The error signal is then used to regulate the excitation current of the exciter stator by increasing or decreasing the current flowing to an, which in turn leads to a decrease or increase in voltage at the main stator terminals.

Different AVR designs - what do they look like?

AVRs all look very similar - they differ slightly in size and color, but they all have similar features.
