R1T, R2T, ... RNT are the resistances measured by the clamp
meter in each grounding branch.
This is a nonlinear system of equations with N unknowns,
N equations. It has a definite solution, but it is very difficult to
solve it manually, and it is even impossible when N is large.
To this end, please purchase our company's finite-point
grounding system solution program software, and users can use
an office computer or a laptop computer to perform the machine
solution.
In principle, in addition to ignoring mutual resistance, this
method does not have the measurement error caused by ignoring
R0.
However, users need to pay attention to this: in your
grounding system, there are several grounding bodies connected
to each other, and the same number of test values must be
measured for the program to solve, not more or less. The
program also outputs the same number of grounding resistance
values.
3.Single Point Grounding System
From the test principle, the clamp meter can only measure the
loop resistance, and cannot measure the single-point grounding.
However, users can use a test lead and a ground electrode near
