Answer Posted / arshad
Remember trip coil is nothing but just a current transformer (CT) with high precision. When excess current flows through line the coil (Rogowski Coil) energies and save/protect the line and instruments.
And shunt closing coil only remote operated and voltage (24VDC, 48VDC, 110VAC, 240VAC) operated. It does not protect line/instruments against over-current/fault.
