Answer Posted / s.karthik
consider the example of CT with the ratio 50:5.
it means if 50amps is flowing in the primary,it will show
only 5 amps in the secondary.Now when the polarity is
changed,50 amps will flow in the secondary which is
comparatively high,and the windings are designed to carry
only 5 amps and hence as a result the windings will burn due
to the volumenous amount of current flowing throught he circuit.
