Answer Posted / animesh daripa
Suddenly disconnected the load from L.T side. The secondary of a current transformer is not disconnected from its load while current is flowing in the primary, as the transformer secondary willattempt to continue driving current across the effectively infinite impedance up to its core saturation voltage. This may produce a high voltage across the open secondary
