    Dumbo2929 - if you want know that have the spreadsheet, you have to read the IEEE Std 80-2000 because the formulas that spreadsheet have is there.

    ground grid design with 3000 ohm-m soil resistivity

    I Think that resistivity is not correct. The first that you must be is reduce the resistivity because is very great. I send you file in exel for calculate the step and mesh voltages.http://files.engineering.com/getfile.aspx?folder=357fc486-5cc1-4ead-a308-3fa45f0be3bc&file=redes_de_tierra.xls
