Avr control on generators generator#

It also helps save the generator from an insufficient battery charge.

Consequently, it makes sure that the generator voltage never drops as low as to result in the malfunctioning of any connected electrical equipment or electrical devices. This, in turn, ensures a lower or higher voltage, respectively at the main stator terminals.Īs you may have understood by now, the AVR works as an adjustment device that ensures that the voltage output of the generator remains within a predefined range. In case of a discrepancy between the two, the ACR adjusts the field current by increasing or decreasing the current flow to an exciter stator. It accomplishes this task by first sensing the voltage from the generator terminals, and then comparing the same to the preset stable reference value to check for the error signal, if any.

Under the alternator’s rear cover (usually in the case of small portable gensets)Īn AVR primarily functions by controlling the generator output voltage.In the main control box of the generator.In general, automatic voltage regulators can be found in any of the following mentioned places – Here, the model of the AVR supplied with the alternator will largely depend on the type as well as the accessories fitted to the alternator. Simply put, the AVR can be said to be an integral part of the alternator’s excitation system.ĭid you know? It is not the generator manufacturer that provides the Automatic Voltage Regulator, but the alternator manufacturer! After all, the AVR is essentially a part of the AC Alternator.

The AVR is designed to facilitate the automatic maintenance of generator output terminal voltage at a preset value, especially when there is a change in the generator load, or the operating temperature of the generator undergoes a shift.
