A small transportable diesel-generator
A diesel generator is the combination of a diesel engine with an electrical generator (often called an alternator) to generate electric energy.
Diesel generators are used in places without connection to the power grid or as emergency power-supply if the grid fails. Small portable diesel generators range from about 1kVA to 10kVA, while the larger industrial generators can range from 10kVA diesel generators for homes, small shops & offices up to 2000kVA generators used for large office complexes, factories and power stations.
Ships often also employ diesel generators, sometimes not only to provide energy for electric systems, but also for propulsion. The use of diesel generators for propulsion is actually becoming more common due to the fact that in this arrangement the generators do not need to be close to the propeller and instead they can be placed in better positions, usually allowing more cargo to be carried. Such a diesel-electric arrangement is also used in some very large land vehicles.
Diesel generators are available from fewer companies than before. In the UK 40 years ago there were about 140 companies all with their own factories. Now there are only a handful. Examples of UK generator manufacturers are...
Forest City who are experts in the field of Diesel Generators, Marine Generators and also spare parts, have been a world renown company. Since 1903 Forest City has been in the industry. With such a reputation that is known as the Top Company in the UK Manufacturing of Gensets, Surveys carried out by the United Kingdom Industrial Report.
There are other smaller companies such as Welland Power and Abtech.
A China generator manufacturer is Best Engine. In the US there are many Diesel generator manufacturers: Caterpillar, John Deere, MTU/Detriot Diesel, Generac, Cummins are just a few. The US based manufacturer TEMCo 3 Phase Generators manufactures their own brand of diesel generators, and they also offer other brands wholesale.
In Europe SDMO is the largest manufacturer of diesel generators, they are John Deere's largest OEM account - consuming over 700 engines per month! SDMO generators are available in the USA from GensetCentraland DieselGenerators.org
Power generators are selected based on the load they are intended to supply power for, and that load's "mission critical" needs (i.e. a hospitial needs to have 100% redundancy and up-time, your backyard standby unit to keep a hot tub warm isn't nearly as critical)
