Coil Permalloy Transformer Core Toroidal 20mm CT Electromagnetic Induction

10*20mm Permalloy Power Coil For Current Transformer

The principle of current transformer is based on the principle of electromagnetic induction. The current transformer is composed of a closed core and windings. Its primary winding has very few turns, which is stringed in the line of the current that needs to be measured. Therefore, it often has all the current flowing through the line. The secondary winding has a relatively large number of turns. It is serially connected to the measuring instrument and the protection circuit, and the current mutual inductance When the transformer is working, its secondary loop is always closed, so the impedance of the series coil of the measuring instrument and the protection loop is very small, and the working state of the current transformer is close to short-circuit
