Hi Ram,

Well, you have certainly picked one of the most obscure thesis to
embark upon. Everyone's done it, they all have an answer, but no one
could repeat it anywhere by any rationale except maybe in one fine
publication:
UNITED STATES DEPARTMENT OF AGRICULTURE
Rural Electrification Administration
REA BULLETIN 1751F-802
SUBJECT: Electrical Protection Grounding Fundamentals

It does not characterize soil, but it does a very compelling job of
characterizing technique, which is very valuable.

I don't know what the soil is like there in Malaysia, but you can bet
that it contains all the variables that will make analysis quite a
challenge. I would presume that you at least have less differences in
water content and temperature than here in North America (this drives
a huge difference in earth resistance).
