Applications

ATO provides earth resistance testers with a measurement range of 0.00Ω-300kΩ, which are widely used in ground resistance measurement and loop resistance measurement in fields such as electric power, telecommunications, meteorology, oil fields, construction, and industrial electrical equipment. When measuring the grounding system with a loop, the ground resistance tester does not need auxiliary electrodes and does not need to disconnect the grounding wire, which is safer and faster.

Clamp earth resistance tester applications Tips: What are the factors that affect soil resistivity?

Soil resistivity is the average value of soil resistance per unit length, measured in ohm meters. The main factors affecting soil resistivity are as follows:
Different soil types have different soil resistivities.
When the temperature drops again, ρ increases significantly. As the temperature starts to rise from 0°C, ρ will only decrease steadily.
The size of the soil resistivity ρ mainly depends on the concentration of conductive ions in the soil and the water content in the soil. The higher the concentration of conductive ions in the soil, the better the conductivity of the soil and the smaller ρ.
The density of the soil affects the soil resistivity.
Seasonal changes will cause changes in soil resistivity, and the most obvious factors affecting soil resistivity are rainfall and freezing.
