As per my knowledge we can design such circuit using CT and OPAMPs, but don't have exact idea so kindly help me in this regards.

Need help to design such circuit,

Is it a requirement that you design/build the unit. Otherwise, commercial units are available and guaranteed to work.... http://www.bender.org/current_relays.aspx

 

well what exactly do you want to do in an over or under current situation?
