Distributed photovoltaic power generation lightning rod grounding wire, how to reduce the resistance? No drag reduction agent. How do you use salt?
The long-term addition of industrial salt to the grounding device can lead to soil salinization and soil pollution, affecting the growth of surrounding plants and even polluting nearby water sources.
It is not recommended to use salt irrigation methods to reduce the grounding resistance, this approach is equivalent to drinking poison.
The increase of electrolyte in soil will also lead to the formation of electrochemical corrosion environment and accelerate the corrosion of grounding materials. So, we often find that the first year of irrigation salt is good, use second years slightly worse, to third years, fourth years, and then how irrigation is not effective, because at this time the ground material has been basically corroded.
Soil salt is added to the soil near the grounding device, and the electric conductivity of the soil is increased, and the soil resistivity is reduced, and the effect of grounding resistance is reduced.
