I am PhD student and I doing some work on grounding resistance and I
would like to develop a formula for CALCULATION OF EARTH RESISTANCE IN
MULTI-LAYER EARTH STRUCTURE. and compare it with some field
measuremnts...What do you think? Is it possible to develop such this
formula?
Just want to remind you again that my case of study (calculation of
Earth resistance for the driven rod in a horizontally stratified
multi-layer earth at non-homogeneous earth).
If any body have any papers to help or any advice please do
I would like to thank you in advance
your Ram


I hope your REALLY good at MultiVariable calculations. As Ground
Conductiivity has a pile of factors that are significant, and a double
pile that are slightly significant. Better get really boned up on your
Soil Chemistry, Ground Water Chemistry, Disolved Minerals, and add data
from Water Tables, and their weekly, monthly, and yearly variances.
Then think about Temp. Humidity, and the like, of the Area that you
trying to model.
Well I guess if your a PHD Candidate, you should have passed Calculus,
somewhere in the past, and maybe this is a good thesis project.

Me Good luck to you..........
