Three-phase electric power (abbreviated 3ϕ ) is a common type of alternating current (AC) used in electricity generation, transmission, and distribution. It is a type of polyphase system employing three wires (or four including an optional neutral return wire) and is the most common method used by electrical grids worldwide to transfer power.

It has a ferromagnetic core, a primary and a secondary winding of copper wire. The phase or neutral wire on which the current to be measured is passed through the CT ring. The AC in the phase wire (primary) produces an alternating magnetic field in the core which then induces an AC in the secondary winding of the CT. ... CT topology in a 3 ...
