What is a diesel generator?
How does a diesel generator work?
A Diesel Generator works by converting chemical energy present in diesel fuel into mechanical energy by using a diesel engine. As the engine runs, chemical energy stored within the diesel fuel is converted to mechanical energy, in the form of a rotating shaft. The engine is usually directly coupled to a single bearing alternator via the engine flywheel, but sometimes in the case of two bearing alternators via a flexible coupling. As the engine rotates, the alternators main rotor spins as the power is transmitted through the mechanical coupling, creating electrical energy in the form of a voltage at the alternator terminals. This energy is produced by a magnetic field from the main rotor inducing a current in the main stator, as the magnetic flux associated with its windings dissects the magnetic field of the stator windings.
The coiled windings, usually made from copper due to its low electrical resistance are in turn connected to the alternators terminals. The electrical load is then in turn connected to the terminals, usually via a switching device such as a MCB, MCCB or ACB.

The electrical load is then used to power devices in your home, office, school, factory or any other installation that requires electrical power. Generators can be used at different ratings depending on the application such as Prime (PRP), Standby (ESP), Continious (COP) or Limited Time (LTP).
