This results in one generator bearing greater load than the other one.Īs a result, load imbalance takes place. If there’s an electrical surge, there may be a drop in generator output voltage. Usually, a parallel operating generator has the same amount of voltage between its parallel generators. Other than regulating output voltage, AVR is also responsible for maintaining the droop voltage when it comes to parallel/synchronous generators. Regulates Droop Voltage in Parallel Generators Thus, your generator, wiring, and electrical equipment remain safe and protected from any kind of electrical or fire hazards. Here are basic functions of AVR in an AC generator: Regulates Output VoltageĪs already discussed, AVR helps regulate the output voltage by taking in a static value so that there is no effect of overload on the output voltage. That’s where an Automatic Voltage Regulator (AVR) comes in! It sets the output voltage at a fixed value so that no such damage takes place. This way, it can result in interference and cause damage to wires, electrical appliances and the generator as well. As it produces alternating current, the electrical energy is not fixed. It works on the principle of electromagnetic induction. Interestingly, AVR of a generator does not only regulate the voltage but also performs various other functions.Īn AC generator converts mechanical energy into electrical energy. AVR comes into the function when the load on the generator is changing and has an effect on the voltage output. It settles the output terminal voltage at a fixed value. Being a solid-state device, it regulates the output voltage. In order to control such conditions and ensure protection from any kind of electric or fire hazards, you need to make sure that your generator’s Automatic Voltage Regulator (AVR) is in good working condition.ĪVR is an electronic device that is present in several appliances to prevent electrical surge. Also, they supply more than desired voltage to your circuit breakers, which sometimes damages any equipment and appliances in use. Generators often experience great damage during electrical surge and overload.
