If the float voltage is very high, it will shorten the life of the battery. Battery chargers are usually made of stainless steel to prevent corrosion.
They are also fully automatic and do not require any adjustments to be made or any settings to be changed. The DC output voltage of the battery charger is set at 2. The battery charger has an isolated DC voltage output that does interfere with the normal functioning of the generator. Control Panel This is the user interface of the generator and contains provisions for electrical outlets and controls.
The following article provides further details regarding the generator control panel. Different manufacturers have varied features to offer in the control panels of their units. Some of these are mentioned below. Constant measurement and monitoring of these parameters enables built-in shut down of the generator when any of these cross their respective threshold levels. All generators, portable or stationary, have customized housings that provide a structural base support.
The frame also allows for the generated to be earthed for safety. Articles and Info Why Use Diesel? New vs. Search for:. How Does a Generator Create Electricity? How Generators Work.
How does a generator work? Engine The engine is the source of the input mechanical energy to the generator. The following are the factors that you need to keep in mind while assessing the alternator of a generator: a Metal versus Plastic Housing — An all-metal design ensures durability of the alternator.
Fuel System The fuel tank usually has sufficient capacity to keep the generator operational for 6 to 8 hours on an average. Turning the rotor makes an electric current flow in each section of the wire coil, which becomes a separate electric conductor.
The currents in the individual sections combine to form one large current. This current is the electricity that moves from generators through power lines to consumers. Electromagnetic generators driven by kinetic mechanical prime movers account for nearly all of U. Most of U. In a turbine generator, a moving fluid—water, steam, combustion gases, or air—pushes a series of blades mounted on a rotor shaft.
The generator, in turn, converts the mechanical kinetic energy of the rotor to electrical energy. Different types of turbines include steam turbines, combustion gas turbines, hydroelectric turbines, and wind turbines. Most steam turbines have a boiler in which a fuel is burned to produce hot water and steam in a heat exchanger, and the steam powers a turbine that drives a generator.
Nuclear power reactors use nuclear fuel rods to produce steam. Solar thermal power plants and most geothermal power plants use steam turbines. Most of the largest U. Combustion gas turbines , which are similar to jet engines, burn gaseous or liquid fuels to produce hot gases to turn the blades in the turbine. Steam and combustion turbines can be operated as stand-alone generators in a single-cycle or combined in a sequential combined-cycle. Combined-cycle systems use combustion gases from one turbine to generate more electricity in another turbine.
Most combined-cycle systems have separate generators for each turbine. In single-shaft combined cycle systems, both turbines may drive a single generator. Learn more about different types of combined-cycle power plants. Combined-heat-and-power CHP plants , which may be referred to as cogenerators , use the heat that is not directly converted to electricity in a steam turbine, combustion turbine, or an internal combustion engine generator for industrial process heat or for space and water heating.
Most of the largest CHP plants in the United States are at industrial facilities such as pulp and paper mills, but they are also used at many colleges, universities, and government facilities. CHP and combined-cycle power plants are among the most efficient ways to convert a combustible fuel into useful energy.
Hydroelectric turbines use the force of moving water to spin turbine blades to power a generator. Most hydroelectric power plants use water stored in a reservoir or diverted from a river or stream.

The power of the engine determines how much electricity a generator can provide. This is where the conversion from mechanical energy to electrical energy occurs.
Fuel System. The fuel system makes it possible for the generator to produce the energy needed. The system includes a fuel tank, a fuel pump, a pipe connecting the tank to the engine, and a return pipe. A fuel filter removes debris before it gets to the engine and an injector forces the fuel into the combustion chamber. Voltage Regulator. This component helps control the voltage of the electricity that is produced.
It also helps convert the electricity from AC to DC, if needed. Cooling and Exhaust Systems. Generators create a lot of heat. The exhaust system direct and remove the fumes the form during operation. Lubrication System. There are many small, moving parts inside a generator. It is essential to lubricate them adequately with engine oil to ensure smooth operation and protect them from excess wear. Lubricant levels should be checked regularly, as often as every 8 hours of operation.
Battery Charger. Batteries are used to start up the generator. The battery charger is a fully automatic component that ensures the battery is ready to go when needed by supplying it with a constant low-level of voltage. Control Panel.
The control panel controls every aspect of generator operation from start up and running speed to outputs. Modern units are even capable of sensing when power dips or goes out and can start or shut off the generator automatically. This is the body of the generator. It is the part that we see; the structure that holds it all in place. Generator Fuel Tanks The fuel system ensures the generator has the necessary raw materials needed to provide electricity by initiating the internal combustion process.
Generator Exhaust Systems and Emissions Controls As machines that burn fossil fuels and run continuously, even if that run time is erratic, generators must be equipped with components to cool them off and to filter emissions. Generator cooling and ventilation systems reduce and remove heat in a variety of ways: Water.
Water can be used to cool off generator components. This type of coolant system is typically limited to specific situations or very large units of 2, kW and higher.
