The coupling of Diesel Engine & Alternator is know as DG
set.
Diesel is used as fuel for diesel Enigne which is also
called as Prime moover for the alernator.
when saft coupled priemoover rotate then due to Faraday`s
Electromagnetic induction law the a rotating flux is
generated cause to generate the EMF Electromagnatic Field.
As alternator is synchronous generator it will run on
constant seep otherwise not at all so for controlling of
it`s speed we usses the AVR Automatic Voltage Regulator.
