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 our company. Users can use
the office computer or notebook computer to carry out solutions.
In principle, in addition to ignoring the mutual resistance, this
method does not have the measurement error caused by neglecting
