Concrete platforms in a substation

Concrete platforms in a substation

RE: Concrete platforms in a substation

The floor has to be paved with concrete plates on a sand bed-except the equipment basis and the access way. You need this to repair or extend the Grounding Grid and cable conduits [or pipe].
Also handholes [or manholes] have to be provided. This is what in a good design it is required.

@7anoter4
Do you have any suggestion for good design (links, documents, codes, examples in the net)?

RE: Concrete platforms in a substation

I have only our experience in Power Station design [about 10 fossil-fuel power stations].But if it is about a large substation you have to fill the area with crushed rock as per IEEE-80 –for instance-in order to produce an insulated layer. In this case you don't need concrete plates. The reinforced concrete presents a low insulation resistance. See: IEEE-80/2000
Ch. 7.4 Effect of a thin layer of surface material

RE: Concrete platforms in a substation

If you have a trawl through this file and search for "civil" or "substation" you'll find the url's of a few excellent reference documents.
