Each automatic voltage regulator has its pros and cons, so it’s important to know what each one is before deciding. When choosing an avr for generator, there are a few different types to choose from. They convert mechanical energy into electrical energy. The AVR utilizes the extra power when supplying non-linear loads such as starting of motors. PMG supplies isolated power to the AVR when the generator shaft rotates. A permanent magnet is mounted on the driven end of the generator shaft. 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. Avr for Generators is the heart of an electrical generator. Generators equipped with permanent magnets are among the most well-known separately excited methods. If there is damage, they will repair it but in cases where damage is beyond re[air, a replacement may be due. They will measure for resistance and check for any damage. This will then be cleaned away or dealt with quickly.Ĭonnectors check for tightness or fastness. This is to check for any signs of damage, burn, or debris. The steps involved in maintenance are as follows: Excitation power is derived from a three-phase permanent magnet generator (PMG), to isolate the AVR control circuits from the effects of non-linear loads. The AVR may require maintenance after a couple of hundred hours of operation but this can vary based on your unique usage. 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. 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.
