At initial condition,we have high armature current,so in order to reduce that we use 3-point starter.
Then after we to kept a constant speed.so if current decreases obviously speed increses.so thats y we decrese the flux/arm current speed increses..

How can you calculate the size of the down conductor cable for the lightning protection system. Is 70mm2 cable can replace 95mm 2 bare copper cable when the copper tape size is 25Wx3 thk mm.
