if transformer winding burn on dc supply then
why not alternator rotor winding please post
answer on y.sakhare@rediffmail.com

Answer Posted / yogesh

every conductor produces magnetic field around it when you give ac or dc supply.but in ac supply the flux is alternating which produces self induced emf in winding which opposes supply vtg so currunt limits.but in dc supply there is no self induced emf.so when dc supply given to xmer no self induced emf produced to limit the current and in alternator or dc motor there also no induced emf produced but to limit the current the winding resistance made high ie above 100 ohms wheres xmer wdg resistance is in points range ie 0.1 ohm etc
