       The operation environment of distribution lines is poor and the failure rate is high. Power failure often occurs due to lightning strike, damage and insulation damage. The troubleshooting is time-consuming and laborious, which seriously affects the user's sense of high-quality power consumption experience. The small current grounding line selection device perfectly solves the problems of line selection and accurate positioning of common grounding faults.

        Each set of low current grounding line selection device of industrial control computer can monitor 60 lines at the same time, and can accurately distinguish the fault line and accurately trip in case of single-phase grounding fault of the monitoring line, and the tripping time can be set; The tripping is a passive contact and its reliable reset shall be ensured. The outlet of each tripping circuit shall be equipped with a tripping outlet pressing plate to facilitate the switching on and off of this tripping circuit.

        Small current grounding line selection can display voltage, zero sequence current, single-phase grounding fault times, date and time, grounding start time, grounding line number, grounding troubleshooting time, etc. all displayed information is in Chinese, and no less than 100 grounding information can be recorded.

        The information collected and generated by the small current grounding line selection device can be provided to remote signals such as background voltage, zero sequence current, single-phase grounding fault times, date and time, grounding start time, grounding line number, grounding elimination time, etc. through network port or serial port communication.
