Simple Measurement of Ground Resistance
This measurement is made to prevent access to auxiliary earthing rods The convenience test method is set here Using an existing grounding impedance A very small grounding electrode such as ground metal water tube, fire hydrant lightning rod, commercial power system Common Earthing and Grounding of Buildings power off and so on for auxiliary grounding rods C and P.
Simple test lines are shown below (re: commercial Common earthing ends such as power systems)
Three-line Measurement of Ground Resistance
Connect the auxiliary rods P and C in a straight line Between 5 and 10 meters into the ground, chain Green line to instrument terminal E, yellow wire to Terminal P and red wire to Terminal C.
Note: Please insert the auxiliary earthing rod in the high water content To encounter dry, sandy, or crushed land. Add water to keep the earthing rods in place Wet, level the earthing rod in case of cement Add water and apply wet towels to earthing rods Up again.
Ground resistance test requirements:
a, ac working grounding, grounding resistance should not be greater than 4Ω;
b, safe working grounding, grounding resistance should not be greater than 4Ω;
c, dc working grounding, grounding resistance should be determined according to the specific requirements of the computer system;
d, the grounding resistance of the lightning protection should not be greater than 10Ω;
e, the grounding resistance should not be greater than 1Ω for the shielding system if joint grounding is used.
Grounding voltage measurement
Please change the range selection switch to the connected low voltage (RAPTHVOLTAGE) file first, please confirm that this voltage value is below 10V, if this voltage value is above 10, then the measured value of the grounding resistance may produce a generation error. At this point, the power off of the equipment using the compared earthing body will be used to reduce the voltage of the connection. The following lines are taken:
High-precision Rapid Detection
The three-wire compensation measurement method is adopted to eliminate the influence of lead resistance
Test Range:0.01-2000Ω
resolution ratio:1Ω
measurement error :±%2rgd/±2dgt
Rapid response measurement
Measuring grounding resistance for about 5 seconds
