The purpose of the zero-sequence current transformer: when an electric shock or leakage fault occurs in the circuit, a protective action is generated to cut off the power supply.
Its use occasion: a zero-sequence current transformer can be installed on each of the three-phase lines, or the three-phase wires can be passed through a zero-sequence current transformer together, or a zero-sequence current transformer can be installed on the neutral line N, Use it to detect the current vector sum of three phases.
Since the cable itself is insulated, the casing of the differential current transformer is also insulated, so the zero-sequence current transformer can be used on cables of any voltage level.
