Introduction:
Mainly used in power extraction, energy conversion, power measurement, leakage protection and so on. Such as: in the power system used in various types of different levels of current transformers, power extraction transformers, current sensors and so on. With superior magnetic properties, in the weak magnetic field has the highest permeability, the bottom of the saturation magnetic susceptibility and high resistivity, consistent performance is better. Wide range of applications.
The principle of current transformers is based on the principle of electromagnetic induction. A current transformer consists of a closed core and windings. It has a primary winding with few turns, which is strung on the current line to be measured. Therefore, it usually has all the current flowing through the line. The secondary winding has a relatively large number of turns. It is connected in series with the measuring instrument and the protection circuit, current mutual inductance When the transformer works, its secondary circuit is always in a closed state, so the series coil impedance of the measuring instrument and the protection circuit is very small, and the current transformer's working condition is close to a short circuit.
