are the resistances measured with the
Meter in the different grounding branches.
It is nonlinear equations with N unknown numbers and N equations.
It indeed has a definite solution, but it is very difficult to solve the
issue artificially, even impossible when N is larger.
Therefore, you’re expected to buy the Limited-Point Grounding
System Solution software produced by this Company. Users can
use the office computer or notebook computer to carry out solu-
tions.
In principle, in addition to ignoring the mutual resistance, this me-
thod does not have the measurement error caused by neglecting
