Method for measuring the grounding resistance of a house

Method for measuring the grounding resistance of a house

Each house, after installation, needs to be tested for compliance. The other reference standard is the grounding resistance value. The next one is to measure the grounding resistance value by the precision four-wire method. Each house, after installation, needs to be tested for compliance.

Guangzhou Energy ES3010E Grounding Resistance Soil Resistivity Tester (simple type) can measure the grounding resistance, soil resistivity, grounding voltage measurement and other functions using the 2, 3, and 4 wire methods. The grounding resistance range can reach: 0.00Ω~30.00KΩ, the soil resistivity range can reach: 0.00ΩM~9999KΩM, and the voltage range is 0~600V. China Hardware Business Network
As shown above: ES3010E standard accessories include: 1 instrument, 1 instrument box, 4 auxiliary grounding rods, 4 test lines, 2 simple test lines, 1.5V battery, 6 sections, user manual warranty 1 out ES3010E Grounding resistance soil resistivity tester China Hardware Business Network This time, the four-wire precision test grounding resistance is used (refer to the following wiring). The distance between the default grounding rods is 5 meters. China Hardware Business Network Ground rod current is extremely red China Hardware Business Network Grounding rod voltage is very yellow China Hardware Business Network Clamp both green and black to the ground lead of the device China Hardware Business Network Insert the corresponding color into the meter interface China Hardware Business Network Overall picture China Hardware Business Network Rotate the switch to the grounding resistor RE, this is the measurement of the grounding resistance China Hardware Business Network Press the TEST red button to start the test. China Hardware Business Network Countdown to 10 seconds, there are still 7 seconds to complete China Hardware Business Network The grounding resistance is obtained, 3.28 ohms, the grounding condition is good at this time, and the inspection is qualified. China Hardware Business Network Measurement completed China Hardware Business Network The above is an example of the operation of the grounding resistance value of the measuring device (simplified) of the Guangzhou Sengeng ES3010E grounding resistance soil resistivity tester (simple type)
