CBCT is Core Balance Current Transformer. it will be having one winding passes over three phases and senses the zero sequence currents there by tripps the circuit through the breaker. its main purpose is to distinguish the earth faults from short circuit faults..i.e its operation depends up on the zero sequence currents that are produced when earth fault occurs.

Please clarify, 1. Is it required to lay two runs of GI wire along with Armoured LT cable if it is laid between one big mains (63Amps TPN SDF) to small main (32A TPN SDF) with proper glanding termination? 2. If the armoured cable with proper glanding is laid from DB to CNC machine, is it required to run two runs of body earthing to the Machine from DB? 3.If the armoured cable with proper glanding is laid from Substation to Hangar, distance is approx. 100 mtrs, is it required to do earthing at shop area though the primary termination at substation is earthed through gland.
