Answer Posted / raul
absolutely NOT bcoz during normal operating conditions, the
primary and secondary current are equal and opposite to
each other.........so the mmf of both primary and secondary
are in direct opposition........but secondary current is a
bit lesser than d primary current and this difference is
utilised in magnetising the core.......but if the secondary
is left opened then there will be no demagnetising mmf left
and excessive flux will b generated in the core and due to
this enourmous amount of voltage will b produced in the
secondary which is very harmful for life and CT also. also
there will be a loss of accuracy in future due to residual
flux left in the core.
