Power generators are backup devices made to provide temporary AC energy by using the supplied fuel, which may be either diesel, gas, or even gasoline. Generators, depending on their own portability, are classified in to two: portable and fixed. Generators are used to convert mechanised energy into electric power. The source of mechanical vitality can vary from internal ignition engine, hand crank, compacted air, and reciprocating vapor engine. An internal combustion motor uses diesel, gasoline, gas gas, and natural gas to create mechanical energy, and this physical energy is converted into electrical energy with the help of generator set up.
