We have AC-transformer 110/13.8kv,40MVA.If DC-Voltage=110kv
is applied in its primary what will happen?
Answer Posted / shivashankar
It will act as short circuit, bcoz the rate of change of
flux will induce voltage in sec,whereas in Dc there is no
such phenomenon ..R=V/I..if V=0 R=0/i ultimately R=0......It
nay tend the transformer to overheat ...
