the grounding resistance paralleled is calculated by the usual
sense. Thus, for the grounding system of N (N is smaller, but larger
than 2) grounding bodies, it can offer N equations:

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
