Embodiment Construction
[0020] Discuss the specific implementation mode below in conjunction with accompanying drawing and embodiment:
[0021] The grounding measurement device is composed of a generating device (1), a receiving device (4), a control device (2), an analysis and processing device (5), a display device (7), a communication device (3) and the like. The generating device (1) is connected to the control device (2), the receiving device (4) is connected to the analysis and processing device (5), the grounding device is connected to the grounding point wire to be tested, and the communication device (3) The control device (2) is connected, and the analysis and processing device (5) is connected to the display device (6).
[0022] The generating device (1) generates impulse current and injects it into the ground loop through the pulse power technology.
[0023] The receiving device (4) collects voltage and current signals in the ground loop through an integrated filter and A / D conversion. ...
