Our customer asked a question: There is a pipeline at the garen plot. I'm going to install grounding. How to make it correctly? Will the grounding electrode set next influence the gas pipeline?
The situation is quite common. We are often approached with the question about the influence of the ground electrode (or rather spreading of the current through this ground electrode) on the pipeline.
The answer to this question is the "working radius" of the ground electrode. For example, the vertical electrode deeper than 5 meters "works" on 90% in the area around it. Thus, the radius of this zone is equal to the length of the electrode.
At the distance of 2 depths, there is a 95% working area of such an electrode.
It turns out that it is necessary to place a vertical ground electrode at the distance of a double length of the ground electrode to neutralize the negative impact on the pipeline.
Installation of the electrode from the pipeline at a greater depth is necessary only in cases of currents of serious power current (for example, lightning current - when connecting the ground electrode (s) to the lightning rod).
