How to measure the grounding resistance of the tower? [ES300

Click:       Source:Zhengneng Electronic

The Essence ES3001 multi-function four-wire grounding resistance tester has: 2, 3, 4 wire grounding resistance, soil resistivity, grounding voltage measurement. USB interface, data upload function, alarm function, data storage 300 groups, grounding resistance range: 0.00Ω~30.00KΩ, soil resistivity range: 0.00ΩM~9999KΩM Voltage range: 0~100V, test frequency: 128Hz, etc. The following is an example of measuring the grounding resistance of a tower.
 
Tower to be measured

Wire as shown below. Red, yellow, green and black, respectively, differ by 5 meters. This is a four-wire method to measure the grounding resistance.
 

 
Ground the rod and clamp the red and yellow test leads to the ground rod.
