| Abstract: | For insulating the leakage current detection problem of equipment supply branch, researching on the application of magnetic phase modulation principle in small DC current sensor, using magnetic phase modulator achieved a feedthrough small DC current measurement. This paper describes the key points of the feedthrough small DC current sensor designs. The performance of AC excitation oscillator circuit directly determines the overall performance. The feedthrough small DC current sensor can effectively solutioned the problem of the equipment insulation leakage current detection. |
