Soil resistivity measurement

[Cesme]

Hi all.

How many measurements do I need for soil resistivity? Some say 2 measurements are enough, while others say 5 measurements are needed (1 for each edge and cross section). What do you suggest? I've even seen 10 measurements. As you know, I'll take the average of these measurements. I want to know the best number of measurements to use.

I assume you’re referring to the amount of traverses for a site. I’ve only seen 2 traverses conducted at different sites, but I could imagine if a site contained a discontinuous soil makeup, more traverses would be a good idea.

That is right, I asked for mostly solar, wind power plants, and power substations. As I understand there is no consensus about number of traverses.

We typically do 9 or 10.

I think you are scanning the area, at the end we are going to take average of measuremnets. I haven't seen any suggestion about traverse numbers. Do you have a special reason for 9 or 10 measurements?
