Abstract:
In modern high voltage substations, earthing has become
one of the dominant problems of AC power system design.
In order to understand the theoretical background and
problems associated with earthing system design, various
international guides were investigated and scrutinised.
This investigation of the theory led to the analysis of
general methods and techniques used for earthing system
design.
Due to the lack and short supply of human expertise in
earthing system design, a computer program was developed
on a Personal Computer, to help enhance and distribute
the needed expertise .
The purpose of this thesis is to provide a complete,
pract i cal and scientific step-by- step guideline to design
a safe and effective outdoor AC substation earthing
system.
