what happens when d cexcitation given to alternator is
removed while it is running or what happens when dc
excitation is failed in alternator while running?
Answer Posted / abubakr
when excitation is lost due to fault or field breaker
tripping . Reactive power will be supplied by the system and
generator will work as induction generator and its speed
will rise a little . generator which was in over excitation
mode will work in underexcitation .
but there is under excitation limit which should not be
reached so we should detect loss of excitation and trip
generator
