Literature and Software on Earthgrid Design

Literature and Software on Earthgrid Design

Literature and Software on Earthgrid Design

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.

RE: Literature and Software on Earthgrid Design

IEEE std 80 IEEE Guide for Safety in AC Substation Grounding. This guide goes through the basics and has reference documents in the appendices. It includes simplified equations that can be used for calculating step- and touch voltages for simple grids in uniform soil.

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.

Many thanks jghrist. Will follow up.

RE: Literature and Software on Earthgrid Design

Veritas, there's an excellent document published by the Energy Networks Association in Australia called ENA EG1-2006 Substation Earthing Guide.

RE: Literature and Software on Earthgrid Design

Bear in mind that whilst IEEE 80 is the de rigeur standard for earthing systems, the methods used to calculate relevant step and touch potential limits in Australia are different now to that which was outlined in IEEE 80. AS2067 now details a different method of calculating the tolerable step and touch potential limits, and as far as I'm aware, its now mandated for almost all HV installations.

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.

Marmite, FreddyNurk

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

RE: Literature and Software on Earthgrid Design

Formulae based on Dalziel's research are used in IEEE80 and ENA EG1-2006 to define 'Tolerable' touch and step voltages for various body weights.
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.
