There are lots of public places that use a generator because it is used as a backup power supply. Some places, such as supermarkets, hotels, and hospitals, use generators to store electricity. For instance, the existence of a generator provides backup electricity for daily activities if there is a power outage.
Different types of 5 kVA generators and their features
Generator 5.5 kVA is a type of AC (Alternating Current) generator which is used to produce an alternating electric current. Usually, AC generators have two wires with positive and negative polarity. A 5 kVA generator silent is a type of DC (Direct Current) generator, which is a machine that is used to produce direct current electricity. It does not have a slip ring, but there are two brushes located on the left and right of the coil. The two ends of the polarized coil will alternately touch the brushes so that the generator will be able to produce direct current. 75 kVA generator and 65 kVA generator can be used as an electricity backup system or "off-grid" (a power source that depends on the user's needs). These types of generators are used by hospitals and industries that require a large and relatively stable source of electricity to operate. 35 kVA generator and 55 kVA generator are mounted on a shaft with a diesel motor, which usually uses a synchronous generator (alternator) to generate electricity. It contains two main operating parts: the magnetic field system and the anchor system. 5kv generator and 25 kVA generator are supported by the AVR (Automatic Voltage Regulator) system, which provides electricity supply for twenty seconds right after a power outage. Inside the AVR, there is a Mutual Reactor (MT), which is a kind of CT (Current Transformer) system that produces an electric current based on the amount of load current passing through it.
Working principles of a 5 kVA generator
A generator does not generate electrical energy but instead uses mechanical energy to move the electric charges. The working principle of the generator is based on electromagnetic induction in which after the rotor is rotated by the prime mover motor, the poles on the rotor will rotate. This situation will then create a voltage difference between the two ends of the electric conductor, which in turn causes electric charges to flow and produce an electric current.
