Please read IEEE standard 80- 2000 This provides complete information about substation earthing.It is about 200 pages and a complete reference for SS earthing.What ever information you require is available in this std.

chapter 8. criteria for tolerable voltage

Chapter 9 gives the complete design criteria for substation earthing.

Thank you Mr Abraham,

Can you tell me where to find IEEE80 and what would be the cost (approx) as I am from a small town in Bihar. In the mean while I will appreciate if you could give me some idea on the topic.

The Soil Resistivity needs to be checked before finalising the grid conductor sizing & spacing.
