Recommended clear zone around substations?
Recommended clear zone around substations?
(OP)
What are the requirements, recommendations or guidelines for the mimimum clear zone on the outside of substation perimeter fencing?
Is the clear zone for maintenance, security, ground grid protection, or other?
Where can I find these requirements or recommendations? Looked in NESC, IEEE, without much luck. Have found some references to a mimimum recommended 20 to 30 foot clear zone for security, but not much else.

An additional clear zone for security doesn't seem particularly useful in either an urban or rural setting. Some of our most expensive substation thefts have occurred from substations where we happened to own large amounts of cleared property around the substation. Vandalism damage from rock throwing has occurred at sites with large clear areas outside the substation fences.
