The zero phase current transformer is a line fault current monitor. Generally, there is only one iron core and secondary winding.

When using, the primary three core cable is passed through the iron core window of the transformer, and the secondary wire is connected to a special relay, and then the output terminal of the relay is connected to a signal device or an alarm system.

Under normal circumstances, the three phase currents in the primary circuit are basically balanced, and the resulting combined magnetic flux is also close to zero. No current is induced in the secondary winding of the transformer.
