Standbypower generators are permanently installed and kept ready to supply power to critical loads during temporary interruptions of the utility power supply. Hospitals, communications service installations, sewerage pumping stations and man other important facilities are equipped with standby power generators. Small and medium generators are especially popular in third world countries to supplement grid power, which is often unreliable. Trailer-mounted generators can be towed to disaster areas where grid power has been temporarily disrupted.
Резервные генераторы энергии постоянно устанавливаются и сохраняются готовыми поставлять власть к критическим грузам в течение временных прерываний сервисного электропитания. Больницы, сооружения обслуживания коммуникаций, канализация насосные станции и много других важных средств обслуживания оборудованы резервными генераторами энергии. Маленькие и средние генераторы особенно популярны в странах третьего мира, чтобы добавить мощь сетки, которая является часто ненадежной. Установленные трейлером генераторы могут буксироваться к областям бедствия, где власть сетки была временно разрушена.

ENGINE-GENERATOR
An engine-generator is the combination of an electrical generator and an engine mounted together to form a single piece of equipment. This combination is also called an engine-generator set or a genset. In many contexts, the engine is taken for granted and the combined unit is simply called a generator.
In addition to the engine and generator, engine-generators generally include a fuel tank, an engine speed regulator and a generator voltage regulator. Many units are equipped with a battery and electric starter. Standby power generating units often include an automatic starting system and a transfer switch to disconnect the load from the utility power source and connect it to the generator.
Engine-generators produce alternating current power that is used as a substitute for the power that might otherwise be purchased from a utility power station. The generator voltage (volts), frequency (Hz) and power(watts) ratings are selected to suit the load that will be connected. Both single-phase and three-phase models are available.
Engine-generators are available in a wide range of power ratings. These include small, hand-portable units that can supply several hundred watts of power, hand-cart mounted units that can supply several thousand watts and stationary or trailer-mounted units that can supply over a million watts. The smaller units tend to use gasoline (petrol) as a fuel, and the larger ones have various fuel types, including diesel, natural gas and propane (liquid or gas).
Engine-generators are often used to supply electrical power in places where utility power is not available and in situations where power is needed only temporarily. Small generators are sometimes used to supply power tools at construction sites. Trailer-mounted generators supply power for lighting, amusement rides etc. for traveling carnivals.
Standby power generators are permanently installed and kept ready to supply power to critical loads during temporary interruptions of the utility power supply. Hospitals, communications service installations, sewerage pumping stations and many other important facilities are equipped with standby power generators. Small and medium generators are especially popular in third world countries to supplement grid power, which is often unreliable. Trailer-mounted generators can be towed to disaster areas where grid power has been temporarily disrupted.
