The voltage regulator then feeds this DC current to a set of secondary windings in the stator, known as exciter windings.
The exciter windings are connected to units known as rotating rectifiers. This cycle continues till the generator begins to produce output voltage equivalent to its full operating capacity. As the output of the generator increases, the voltage regulator produces less DC current. When you add a load to a generator, its output voltage dips a little. This prompts the voltage regulator into action and the above cycle begins. The cycle continues till the generator output ramps up to its original full operating capacity.
It is essential to have a cooling and ventilation system to withdraw heat produced in the process. Hydrogen is sometimes used as a coolant for the stator windings of large generator units since it is more efficient at absorbing heat than other coolants. Hydrogen removes heat from the generator and transfers it through a heat exchanger into a secondary cooling circuit that contains de-mineralized water as a coolant. This is why very large generators and small power plants often have large cooling towers next to them.
For all other common applications, both residential and industrial, a standard radiator and fan is mounted on the generator and works as the primary cooling system. It is essential to check the coolant levels of the generator on a daily basis. The cooling system and raw water pump should be flushed after every hours and the heat exchanger should be cleaned after every 2, hours of generator operation.
The generator should be placed in an open and ventilated area that has adequate supply of fresh air. The National Electric Code NEC mandates that a minimum space of 3 feet should be allowed on all sides of the generator to ensure free flow of cooling air. Hence, it is essential to install an adequate exhaust system to dispose of the exhaust gases. Exhaust pipes are usually made of cast iron, wrought iron, or steel.
These need to be freestanding and should not be supported by the engine of the generator. The exhaust pipe terminates outdoors and leads away from doors, windows and other openings to the house or building. You must ensure that the exhaust system of your generator is not connected to that of any other equipment. Low as well as high power requirements can be met easily by choosing an ideal electric generator with matching power output.
Fuel: Multiple fuel options such as diesel, petrol, natural gas, LPG, etc. Portability: There are generators available in the market which have wheels or handles fitted on them so that they can be moved from one place to another easily.
Noise: Some generator models have noise reducing technology, which allows them to be kept at close proximity without any noise pollution problems. Read More News on electromagnetic induction renewable energy uninterrupted power supply Noise pollution electric generator.

The Engine: The more powerful the engine is in a generator, the more power it will produce. Larger generators functions run on diesel. The Alternator: The alternator includes a stationary component called the stator, and a second moving component called the rotor.
It is the rotor that produces a rotating magnetic field in one of several ways. It usually depends on the size of the generator. Large generators, for example, produce the magnetic field by induction. Small generators may use a permanent magnet. Alternators may also use an exciter, powered by a small source of direct current DC using rings and brushes.
