    7.2. Measurement Grounding Impedance Of The Grounding Grid 7.2.1. Inclined angle method In general, the measurement of grounding impedance of large grounding devices adopts the mode of the included Angle arrangement of the current and voltage line. Generally, the distance between current pile C and the tested grounding device edge d should be 4~5 times of the diagonal length of the grounding grid.

    It can put in a human body simulation resistance Rm inside the frequency selective voltmeter. (Note: the frequency selective voltmeter need to purchase extra.) Test mode selection: Stp.V/Tch.V VF 1A 7.2.6. The instrument verification During instrument verification, a resistance of more than 20 ohms must be connected at the output end of C1 to simulate the resistance of field current pile, otherwise may cause the measurement data error too large, or cause the instrument may be directly protected.
