12 Jul What is a Diesel Generator?
The explanation below is a higher level description and many processes and controls are required to produce stable electricity at the correct voltage and frequency.
A generator is a device for producing electrical energy on-demand.
It is used as back-up to the mains electricity supply and will automatically start and provide electricity for as long as the outage lasts, provided it is fitted with an automatic transfer switch.
A generator‘s main component is a compression ignition diesel engine, that rotates an alternator. This alternator contains a rotating mass of copper (rotor) and a stationary magnetic field (stator). When the rotor turns within the magnetic field, it produces electricity at the alternator terminals.
