A 200 kW Caterpillar diesel generator set in a sound attenuated enclosure used as an emergency backup at a sewage treatment substation in Atlanta, United States. A diesel generator (DG) (also known as a diesel GenSet) is the combination of a diesel engine with an electric generator (often an alternator) to generate electrical energy. [1]
The mid-size stationary engine–generator pictured here is a 100 kVA set which produces 415 V at around 110 A. It is powered by a 6.7-liter turbocharged Perkins Phaser 1000 Series engine, and consumes approximately 27 liters of fuel an hour, on a 400-liter tank. Diesel engines in the UK can run on red diesel and rotate at
At that instant, the circuit breaker connecting the generator to the system may be closed and the generator will then stay in synchronism with the system. [ 3 ] An alternative technique used a similar scheme to the above except that the connections of two of the lamps were swapped either at the generator terminals or the system terminals.
A standby generator is a back-up electrical system that operates automatically. [1] Within seconds of a utility outage an automatic transfer switch senses the power loss, commands the generator to start and then transfers the electrical load to the generator. The standby generator begins supplying power to the circuits. [2]
A steam–electric power station is a power station in which the electric generator is steam-driven: water is heated, evaporates, and spins a steam turbine which drives an electric generator. After it passes through the turbine, the steam is condensed in a condenser. The greatest variation in the design of steam–electric power plants is due ...
The most popular 7 kWe home backup generator (not CHP) operated at an electrical efficiency (LHV based) of 21.5%. The price of the emergency backup generator was an order of magnitude lower than the 5 kWe generator, but the projected life span of the system was over 2 orders of magnitude lower.
It is also known as a unipolar generator, acyclic generator, disk dynamo, or Faraday disc. The voltage is typically low, on the order of a few volts in the case of small demonstration models, but large research generators can produce hundreds of volts, and some systems have multiple generators in series to produce an even larger voltage.

The unit "var" is allowed by the International System of Units (SI) even though the unit var is representative of a form of power. [8] Per EU directive 80/181/EEC (the "metric directive"), the correct symbol is lower-case "var", [ 1 ] although the spellings "Var" and "VAr" are commonly seen, and "VAR" is widely used throughout the power industry.
