Answer / rajevaibhav

Every Generator needs field supply in Rotor. Exciter has
two main parts One is Pilot excitor and other is Main
Excitor. Pilot Excitor consists of Permanent Magnet which
will produce AC Voltage in stator. This voltage is passed
through AVR and Rectifier and given back to the stator of
the Main Excitor, which will induce the AC voltage in
Rotor. This Voltage is passed through the Diode Rectifier
wheel assemble which is mounted on same shaft and Rectified
voltage is given to the Rotor of Generator.
Please note that this ans is relavent to the Power Plant
Generator not DG.

Answer / kj

The above answer is true for DG set also. But sometimes on
small DG the output voltage is used instead of the Pilot
Exciter.

the current will vary with load and also the manufacturer
of the DG.

Often now 1-4 amps but some are 20 to 30 amps.
