| Abstract: | In order to meet the reliable grounding, a set of maintenance testing ground intelligent warning device was developed. The hardware circuit and software process were presented. The device can real-time detect the reliability of grounding equipment, and judge the unreliable （disconnected or abnormal ）grounding, and can immediately cut off test power and alarm. From safety considerations and based on human reaction time, the interruption time is less than 5 seconds. |
