Calculation of TT-MK-A low resistance grounding module usage
Based on years of practical experience in using grounding modules to construct grounding grids, the following formula for calculating module usage is summarized:
ρ·M
The calculation result is rounded to an integer when it is a decimal.
Rn·K
In the formula: n is the number of grounding modules.
ρ - Soil resistivity.
M - module grounding coefficient, with a value range of 0.12~0.16. The larger the soil resistivity ρ, the smaller the value of M.
Rn - Grounding resistance value of the grounding network design.
K - Utilization coefficient, with a value range of 0.7~0.85. The more modules there are, the smaller the value of K.
The relationship between the values of various coefficients can be referred to in the following table:

Performance characteristics of TT-MK-A low resistance grounding module
(1) Corrosion resistant, non-toxic, long service life, easy installation, reducing construction workload;
(2) Capable of absorbing moisture and moisture, with low grounding resistance;
(3) The resistance to high current impact does not increase, and there is no hardening, brittleness, or fracture phenomenon;
(4) Can effectively reduce the grounding resistance of high resistance soil;
(5) The grounding resistance is less affected by the season, and the resistance value can remain stable for a long time.
