woox electrical components Germany woox model woox price

woox 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 in the circuit where the current needs to be measured. Therefore, it often carries the full current of the line. The secondary winding has more turns and is connected in series in the measuring instrument and protection circuits. When the current transformer is in operation, its secondary circuit is always closed, so the impedance of the coils in series with the measuring instrument and protection circuit is very small, affecting the operating state of the current transformer.
