Generator AVR stands for the automatic voltage regulator and it is an electronic device that automatically maintains the electrical output of your generator at a set value or level. Reactive Generator’s team of experts can easily and quickly install an AVR so that it is able to manage the output as the generator load or operating temperature changes. The AVR also forms part of the alternator’s system. Normally, you can find the AVR in a couple of common places in the system. The AVR will either be installed in the main control box, the alternator’s terminal box and or somewhere near the alternator’s cover.
How does the AVR work?
The AVR controls output by sensing the slightest voltage change from generator terminals and comparing it to a stable reference. It will then adjust the field current by increasing or decreasing the current flow to an exciter stator. It is very important for generator owners who wish to maintain a set voltage value because it will regulate and maintain it. Unregulated voltage can cause a spark or any other degree of electrical fault which will affect the utilities, equipment, and machinery powered by the generator. Give us a call and we can discuss the installation, repair, or maintenance of your AVR because it guarantees that the load current is consistent. This helps in eliminating the damage caused by fluctuations.
Everything a generator AVR can doBook a service
An AVR is a part of the alternator excitation system and that means it is part of a crucial piece of equipment in the generator. It is dangerous and unsafe for unqualified technicians to handle this part of the generator and it should only be dealt with by licensed professionals. The AVR may require maintenance after a couple of hundred hours of operation but this can vary based on your unique usage. The steps involved in maintenance are as follows:
The technician will remove the cover. This is to check for any signs of damage, burn, or debris. This will then be cleaned away or dealt with quickly.
Connectors check for tightness or fastness. They will measure for resistance and check for any damage. If there is damage, they will repair it but in cases where damage is beyond re[air, a replacement may be due.
Test voltage regulating capability. As the engine operates, the technician will check the AVR to see if it is operating at the right speed and if it isn’t, it may be a sign that the current breaker contact is not disconnected.
