A zero-flux current transformer is used to measure a current flowing in a conductor (so-called primary conductor). The zero-flux current transformer has an electrical detection winding with which the magnetic flux generated by the flowing current and surrounding the conductor is measured. The zero-flux current transformer further has an electrical compensation winding, with which the magnetic flux...

Mu-metal shield case for transformer in flux-gate which made with high magnetic permeability soft magnetic alloy Mu-metal. The Mu-metal provides a low reluctance path for magnetic flux, popular application in magnetic shields against static or slowly varying magnetic fields. Such type power transformer shield case are trends in new-energy field. Coilcore's produce Magnetic Mu-metal shields fo...

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...
