what will happen if field winding supply of synch generator
accidently got disconnected?

Answer Posted / pankaj agarwal

there are two scenarios one in which it is running in
islanding and other in which it is interconnected with
other system. in case one as field is cut there will be no
supply of exciting current and terminal voltage will fall
to zero. also turbine will tend to overrun as there is
sudden removal of load.
in case two as it is interconnected the stator is still
excited and it will behave like induction generator.

Can u explain : what is supply for train (whether a,c or d.c ).I know that supply is 25000v a.c .But there is rumour that supply is D.C. And also explain how lights and fans inside the trains are working ,and what type of motors are used in trains whether D.C motors or induction motors .If d.c motor, how it gets supply.If traction motors are used then what are traction motors and its functions and how it differs from other motors and also explain about locomotive . y d.c series motor in train.train wheels r driven by D.C shunt motor ,at what voltage,and at what speed. please reply..............
