Soil is the world's most largely available resource; unless you are in
the middle of the ocean, you always have access to the earth's soil.
When most people think of soil, they think of tilling, farming and
something that can be made into a foundation for construction. Most
people forget that soil has electrical properties; these conductive
properties are put to practical use in industrial plants and
manufacturing.
What Is Surface Resistivity?
To put it simply, the term “earth resistance” describes how easily soil passes current. When compared to other conductors like copper or steel, the earth is a bad conductor of electricity. But, there are some application where the earth's conductivity is good enough. If an area is large enough to create a path for current, then the earth can be used as a conductor. When used properly, the earth's soil becomes an indispensable part of electrical systems. Soil is cheap and abundant; this makes is a wise choice when materials cost too much money.
When soil is measured for resistivity, the readings can be used to find the effectiveness of ground grids; these grids are used in conjunction with electrical systems to protect workers and the equipment they use.
Resistivity is also used in prospecting; people can use the measurements to find different resistance values. The values can be useful in determining what types of materials are below the soil; it's an easy way to find specific information about what lies below the earth's surface.

Resistivity For Large Ground Systems
Large ground systems can be found in many industrial buildings; these systems are an essential safety mechanism that protects the electrical supply network. Ground systems make sure that all protective devices work when there is a swell in ground current.
Substations only work when the soil that they are built on has a low ground resistance; this reduces excessive voltages that develop during a fault. When a ground system is installed, it is necessary to measure the resistivity of the surrounding soil.
Inaccurate tests can lead to damage and large repair costs. Soil resistivity can change; therefore, it is important to regularly schedule tests. Corrosion or changes in resistivity can lead faults in a grounding system. The best way to check the soil is to use a resistivity meter; portable meters give people accurate readings that show resistivity through many layers of soil.
