I've been asked to design an addition to a 69kV substation. The area within the substation fence where the addition equipment will go is currently wooded. For political reasons the owner of the electric distribution system is reluctant annoy the local residents and so wants to keep as many trees within the substation fence. These 30-50 trees would be within 15 feet of a 69kV 54mvar capacitor bank.
Typical practice at all other station is to totally clear all vegitation within the fence and landscape around the exterior. Exterior trees are trimmed of any branches overhanging into the substation area.
I have been unable to find a standard that clearly states the vegitation within a station should be cleared. Is this such an intuitively good common sense practice that no one has seen the need to publish it? Any guidance to a standard that I could quote to prove my point would be appreciated.
