Excitor produces AC suply which is converted into DC by means of retifier or simply diode bridge.This DC is provided to rotor magnetic field winding producing stong field because DC peak value is high and it is constant.Thus induces Current in the stator armature conductors.In this way,exciter excites the
Generator

A 400 V, 50 Hz, Δ connected synchronous generator has a field reactance of 0.1 Ω and armature resistance of 0.015 Ω. At full load, the machine supplies 1200 A at 0.8 pf lagging. Under full-load conditions, the friction and windage losses are 40 KW and the core losses are 30 KW. What is the machine’s overall efficiency? Ignore any field circuit losses.
