| Abstract: | In order to solve the problem of fault location of single-phase-to-ground for distribution networks,the signal detection device is designed and realized in this paper,The magnetic field detection is taken to get the current signal.The active filter chip is used to process the signal by connecting a second-order band-pass filter.MSP430 microcontroller is chosen to process the data and display the result.The circuit structure is simple,low in power consumption,and fit to be used on portable devices. |
