Multipoint zero magnetic flux technology

The magnetic core reaches the magnetic balance state by excitation. When the measuring current flows through the wire, breaking the magnetic balance, the flux gate will generate the excitation current, and the signal will drive the compensation coil after amplification, so that the magnetic flux in the magnetic core and the magnetic flux generated by the measuring current will cancel each other and remain in the "zero" state, that is, the so-called "zero flux" state.
