3 terms

3.1 Grounding resistance meter A meter used to measure the resistance between a ground conductor and earth. 3.2 Ground resistance The resistance between the ground conductor and the earth. The increased potential of the conductor when the AC test current flows through the ground conductor Divided by the test current, the quotient is the value of the grounding resistance. 3.3 Auxiliary Grounding Resistance When measuring the grounding resistance, the resistance between the auxiliary grounding electrode used as the potential terminal and the current terminal and the ground. 3.4 Ground voltage The interference voltage on the ground conductor is excluded by the voltage generated by the test current.

4 Overview

4.1 Use The grounding resistance meter is mainly used to directly measure the grounding resistance and soil resistivity of various grounding devices. 4.2 Principle The working principle of the grounding resistance meter is divided into reference voltage comparison type and reference current and voltage drop type.
