The zero-flux current transformer is also called a magnetic balance current transformer. Based on the electromagnetic induction principle, the theoretical error of the zero-flux current transformer is equal to zero, and there is no ratio difference and angle difference. In order to eliminate the influence of the excitation current on the measurement accuracy, the zero-flux current transf...

The four-phase common mode choke is a four-terminal device, which founded by a nanocrystalline magnetic toroidal core as a common mode interference suppression device, four sets same size, same turns numbers coils wound symmetrically. When the common mode current flows, the magnetic flux in the magnetic ring superimposes each other, resulting in a considerable inductance, which has a suppressing e...
