DS-2DJ Cable grounding type fault indicatorDetailed product description：

The DS-2DJ cable grounding fault indicator samples the first half wave of the capacitive current at the moment of grounding and the first half wave of the voltage at the moment of grounding, compares their phases, and when the capacitive current at the moment of sampling grounding suddenly changes and exceeds a certain value, and is the same as the first half wave of the voltage at the moment of grounding, and the conductor to ground voltage decreases, it is judged that the line has been grounded. Otherwise, the line has not been grounded.
