Literature and Software on Earthgrid Design
(OP)
Hi
Any recommendations on good literature on Substation Earthgrid Design for beginners? Also, software packages that does same and do not cost you an arm and a leg?
I live in the IEC world (Australia).
Thanks.

You can probably find inexpensive spreadsheets that use the IEEE 80 simplified equations, but to get detailed results, the software cost at least one arm and one leg.

That said, the relevance is only in terms of calculating tolerable step and touch limits, the actual process for designing earthing grids hasn't changed.

Your input is much appreciated. Will certainly follow up as well. Many thanks.

AS2067 Section 8 should be used in Australia which uses 'tolerable' touch and step voltages based on more recent research done by Biegelmeier.
SKM Groundmat software has the option of both the Dalziel and Biegelmeier methods.
