| Abstract: | This paper introduces a kind of differential magnetic sensor, which is applied to the line selection in fault detection of DC power system. Theoretical research and spot operation verify that this sensor can detect the magnetic field generated by leakage current of each branch without injecting any signal into DC operating circuit,so it has no any bad effects to the circuit. With accurate detection and high sensitivity, it solutes the practical problems on fault detection of DC power system. |
