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

In Power Line Communication (PLC) the wave trap is used to block communication signals from entering neighboring lines. My question is this: Why do they allow for different filtering arrangements on these wave traps? Isn't it always going to be a low pass filter since we want the power frequency to go through, and the comm signal blocked?
