2.4 Measurement Procedure
Example with actual measured values
The following provides an example with actual measured values.
The more grounding electrodes there are in the multiple-
grounded installation, the higher the accuracy of the obtained
values. Alternately, if even one grounding electrode has a small
value (for example, 1 Ω), accurate values can be approached
even if there are few grounding electrodes. Since most multiple-
grounded systems have a large number of grounding elec-
trodes, the error can be limited.
