Earthing resistance calculate8/31/2023 The calculator is suitable for calculations in the event that vertical grounding electrodes are used. The implementation of these designs is carried out in several soils with different resistivity values, to proceed to measure the resistance of grounding and to check with the theoretical calculation. Ground Resistance Calculation Online This calculator allows you to quickly calculate online the total resistance of the grounding system to the spreading of electric current (R). Various mathematical expressions are developed to calculate the. This resistance mainly depends on the geometric shape of the system itself, its electrical properties and the characteristics of the surrounding environment. This report discloses the modification of the Schwarz equations presented in the IEEE 80-2013 standard, in order to calculate the ground resistance of two and three rods connected in line, and three rods connected in triangle. The smaller the value of the earthing resistance, the easier the current dissipation through the earthing system. The implementation of these designs is carried out in several soils with different resistivity values, to proceed to measure the resistance of grounding and to check with the theoretical calculation.ĪB - © 2017 IEEE.
