than its IEC parallel output value). But because a tower-grounding hemisphere was much smaller than the distance between the towers, and with a great number of locations after all, R is much smaller than R . Therefore, it can be justified to assume R =0 from an engineering perspective. -

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. - Page 20 As the resistance value measured by the Meter is the value of the series resistance from the testing line and two grounding resistances. Where: R is the resistance value measured with the Meter. is the resistance value of the testing line. Meter can measure out the resistance value by connecting the test lines with both ends.

In the above three steps, the reading measured in each step is the value of the two series grounding resistance. In this way, we can easily calculate the value of each grounding resistance: From: R1=RA+RB R2=RB+RC R3=RC+RA We get: RA=（R1+R3-R2）÷2 This is the grounding resistance value of the grounding body R To facilitate the memory of the above formula, these three grounding bodies scan be viewed as a triangle;... -
