The introduction of the working principleIn the figure is the working principle circuit of magnetic compensatory current sensors. Accroding to the Ampere's law, the current under test will generate a field B2, and the field is compensated by the field generated by I2M2 and kept balanced, i.e I1M1=I2M2, so I2=I1M1/N2. When N1/N2 spot is determined, I2 is proportional to I1, and it is switched into a voltage signal by Rm and output. The Hall elements is testing the zero flux all the time.
