A Small-Scale Current Sensor Scheme of Single-Loop Double-Winding Fluxgate

This subject designs a single-loop fluxgate current sensor with permalloy as the magnetic core for weak current measurement. The weak DC signal is converted into a voltage signal through the fluxgate and the voltage waveform data is processed and converted by Labview software. Using this design scheme to measure the depolarization current of the main insulation of high-voltage motors, the results show that this design scheme has higher accuracy and higher application value.
