They will protect if they are designed for protection. (not just for monitoring). Also cable rating shall be checked to ensure its protection.

RELAY WILL ACT DEPENDS ON THE SECONDARY CURRENT ONLY, BUT MY QUESTION IS, IF THE LOCATION OF THE CT IS IN GENERATOR NEUTRAL SIDE OF WINDING, THIS PROTECTION MEANS ONLY FOR THE WINDING OF THE GENERATOR OR IT WILL PROTECT ALSO THE CABLE?
