The fuel tank usually has sufficient capacity to keep the generator operational for 6 to 8 hours on an average. For commercial applications, it may be necessary to erect and install an external fuel tank.
All such installations are subject to the approval of the City Planning Division. Click the following link for further details regarding fuel tanks for generators.
Common features of the fuel system include the following: a Pipe connection from fuel tank to engine — The supply line directs fuel from the tank to the engine and the return line directs fuel from the engine to the tank. When you refill the fuel tank, ensure metal-to-metal contact between the filler nozzle and the fuel tank to avoid sparks.
The fuel pump is typically electrically operated. Voltage Regulator As the name implies, this component regulates the output voltage of the generator. The mechanism is described below against each component that plays a part in the cyclical process of voltage regulation. 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.
This is a slight oversimplification, but it paints a helpful picture of the properties at work in a generator. A water pump moves a certain number of water molecules and applies a certain amount of pressure to them.
In the same way, the magnet in a generator pushes a certain number of electrons along and applies a certain amount of "pressure" to the electrons. In an electrical circuit, the number of electrons in motion is called the amperage or current , and it's measured in amps. The "pressure" pushing the electrons along is called the voltage and is measured in volts.
For instance, a generator spinning at 1, rotations per minute might produce 1 amp at 6 volts. The 1 amp is the number of electrons moving 1 amp physically means that 6.

Team ProductLine. How do electric generators work? The engine is used to rotate the axle of an electrical conductor in a magnetic field which creates electricity. Alternator or genhead - creates the electrical output from the engine generated mechanical energy.
The mechanical energy is used to rotate a copper coil wrapped around an iron core inside powerful a permanent magnet or electric magnet.
