Ground Grid Design Rules

[karls2]

Hello,
I'm used to made calculation notes on ground grid design. but I would like to know what are the basic and advanced rules for design the ground grid (before improve it and validate or not trough the calculatuion note).
For example how many meters arround the building for substations, how many meters around transformers and so on.
I know the IEEE 80 200 for the calculation notes but Is there an equivalent for the rules of the design ?
Thanks by advance for your advices.

Except IEEE Std 80/2000 see:
IEEE Std142/2007 Grounding of Industrial and Commercial Power Systems ch.1 System grounding
IEEE Std 665/95 Guide for Generating Station Grounding
IEEE Std 399 Recommended Practice for Industrial and Commercial Power Chapter 14 Ground mat studies [ul]
