Dear all,
Do you know of any useful information or literature in relation to high voltage substation earthing, concept, design criteria, testing and commissioning etc.
Thanks and merry Christmas and Happy New Year.

I tried searching first, and I was supprised that there were nothing under "earthing" and the topics under "Grounding" was limited to one. However thanks for the advice. Do you have a link to the standard?
RE: High Voltage Substation Grounding (Earthing)
Some standards, but you'll have to search their websites:
IEEE Std 80-2000 IEEE Guide for Safety in AC Substations Grounding. (www.ieee.com)
IEC 60479 Effects of current passing through the human body. (www.iec.ch)

Hi,
European standard is HD 637 S1:1998-12.
Just for reference, you can check on this Italian site (sorry it is in Italian language):
www.ele
CEI 11-1 (assimilated by HD637) is the Italian standard about electrical system up to 1 kV.

What voltage-level do you classify as high voltage ?
Maybe a little off-track, but check the IEEE Green Book:

RE: High Voltage Substation Grounding (Earthing)
If my memory serves me right, IEC classifies 33kV to 220kV band as High voltage (and beyond extra-high voltage).
RE: High Voltage Substation Grounding (Earthing)
Thanks, I actually want to know at what voltage-level the originator of the question is talking about.
I do have some pdf-files from Eskom (Local South-African electricity supplier) for MV-substation earthing. (up to 44kV)
Regards
Ralph
RE: High Voltage Substation Grounding (Earthing)
Thanks for your responses. I am talking about 132 230 and 330KV. I have IEEE Green book and I will appreciate if you could send me the link to the ESKOM document.
Merry Christmass to all.

IEEE Std 80-2000, IEEE guide for safety in AC substation grounding
----------------------------------------------------------
Abstract:
Outdoor ac substations, either conventional or gas-insulated, are covered in this guide. Distribution, transmission, and generating plant substations are also included. With proper caution, the methods described herein are also applicable to indoor portions of such substations, or to sub-stations that are wholly indoors. No attempt is made to cover the grounding problems peculiar to dc substations. A quantitative analysis of the effects of lightning surges is also beyond the scope of this guide.
This is a full size book and is available from http://shop.ieee.org/ieeestore/, but not for free.

May not be exactly what you want but it's free.

From the Introduction to IEEE std 80-2000:
"Major modifications include the further extension of the equations for calculating touch and step voltages to include L-shaped and T-shaped grids; the introduction of curves to help determine current division; modifications to the derating factor curves for surface material; changes in the criteria for selection of conductors and connections; additional information on resistivity measurement interpretation; and the discussion of equations for the calculation of grid resistance, and the annexes."
