What is Ground Resistance?
How is Ground Resistance Measured?
It is the reaction shown by the soil when it conducts electric currents. Accordingly, it is a weaker conductor than conductors like copper. However, it should be known that if the current is large enough, the resistance is low and the soil can become a good conductor. For these reasons, there must be resistance between the conductors in the systems and the soil. Before the installations are set up, ground resistance measurements are made, and after the necessary calculations and preparations, the installation work is done. These services should be carried out as Gebze grounding measurement by engineers and expert companies.
What is Soil Resistance and How is it Measured?
Gebze grounding measurement and resistance must be carried out by expert and experienced engineers. Accordingly, the most frequently used method in resistance measurements is the 2-stake measurement method. P and C electrodes are driven deep into the ground, and the distance between these electrodes should be 5-10 meters. A green cable is connected to the grounding bar, and the bar must be separated. Also, the soil where the electrodes are driven must be moist. The resistivity of the soil is the resistance of the soil. Its value depends on the structure of the soil and the amount of water it contains. The transition resistance of an electrode to the ground depends on the resistivity of the soil. The insulation of each conductor to the ground should be measured with ground resistance test measuring devices, and the insulation of the conductors to each other should be measured with insulation test measuring devices. In addition, it is of great importance that Gebze grounding measurement and necessary services are carried out by expert and authorized persons in their field.
