Answer Posted / tameshwar singh
The CT saturation occurs when secondary winding is kept
open. At this time there is no demegnatising current flows
in secondary winding and due to this primary winding will
carry very high megnatising current.As the high megnatising
current produces high megnatic flux which causes the CT
core saturation
