Soil Resistivity Testing 10 Common Mistakes
This is a series of short posts on Soil Resistivity Testing and the common mistakes encountered, with practical advice on how to avoid Soil Resistivity Testing 10 Common Mistakes.
The Soil resistivity can be determined using different Soil Resistivity Testing methods Driven Rod, described below is the last of the three most popular Soil Resistivity Testing methods used to measure the soil resistivity
Driven Rod Method
This method is also called the three probe method or three pin method .
This method is most suitable for an area where the physical layout makes the usage of the previous two methods difficult; the soil resistivity under this method can be calculated using equation 3:
l is the length of driven rod in contact with the earth
d driven rod diameter
