AC-Marine electrical components are instruments that convert high primary current to low secondary current for measurement based on the principle of electromagnetic induction. A current transformer consists of a closed iron core and windings. Its primary winding has very few turns and is connected in series with the circuit where the current needs to be measured. Therefore, the full line current often flows through it. The secondary winding has more turns and is connected in series with measuring instruments and protection circuits. When the current transformer is in operation, its secondary circuit is always closed, so the impedance of the coils connected in series with the measuring instruments and protection circuits is very small, current transformer
