RE: calculation method,number of rod

Hi Elmay,

Do you know the type of soil or has anyone done a soil resistivity test?

RE: calculation method,number of rod

IEEE 80 is one of the more useable standards, although you will need some idea of soil conditions as noted by AusLee in order to use the calculation methods. The IEEE 80 calcs are fairly simplistic and computer software exists which can produce much better modelling results if you have good data to feed in.
