What does “grounding” mean?
Grounding means making an electrical connection between an electrical device or a building and the earth underfoot. Properly grounding equipment and buildings helps ensure safety by preventing electric shock and related accidents. It also heps prevent the occurrence of har- monics, equipment malfunctions, power outages, and other issues with power supply quality. During installation and maintenance, it’s critical to make sure the ground resistance values of your grounding equipment conform to the values specified by applicable laws and standards
Pic.: HIOKI FT6041-91 EARTH TESTER Field-capable Fast-working Extensive measurement functionality
− 4-pole method (Wenner’s 4-pole method):
Measure soil resistivity when surveying a grounding design
− 3-pole method:
Precisely measure ground resistance
− MEC (Measuring Earth with a Clamp) function:
Measure ground resistance without disconnecting ground electrodes
− 3-pole method using 4-terminal measurement:
Measure ground resistance values of several ohms or less
− 2-clamp method:
Measure grounding resistance at multiple grounds
− Low-resistance measurement:
Continuity test after ground resistance measurement
4-pole method
Measure soil resistivity when surveying a grounding design
Soil resistivity is measured as part of the grounding design process in advance of building design. Soil resistivity varies with each site’s geo- logical properties. In this process, optimal ground locations as well as grounding electrode shapes, dimensions, and other characteristics are designed based on the assessed soil resistivity.
MEC function
Measure ground resistance without disconnecting ground electrodes
This function augments the 3-pole method with current measure- ment using a clamp sensor. By measuring only current flowing to the grounding electrode you wish to measure, you can avoid the effects of other grounds. This capability can substantially reduce man-hours spent on measurement work.
