Grounding training
(OP)
Does anyone know where I can find a GOOD substation grounding course? Preferrably in a classroom setting, but an online course, or even a tutorial cd/dvd will do. My company has training, but not on specific topics such as grounding. If anyone can recommend such a class, etc, it will be greatly appreciated.
I'm located in NYC.

Ground grid design, ground system testing, or personal protective grouding (Equipotential Grounding)?
I know a good course for 2 of those topics.

jghrist: thanks, but i'm in NYC. i dunno if my company will pay for an out-of-state course. i'll ask them, though.
zogzog: thanks. would you send me some info?
RE: Grounding training
They wont be in NYC or NY, or east coast even. Unless you get lucky and hit the scheduled remote class.
RE: Grounding training
In the event I cannot get to a traditional class, I'm open to an online class, or even some sort of "training series" on DVD.
anyone?

My company is building new substations and we are generally copying what was done for the previous stations. While I think that copying is good for scheduling and deadlines, I don't think we get a good enough understanding about the various systems by copying.

This is a good equipotential grounding seminar, but not in NY, I dont think you will find anything there.

Maybe I should've noted that we have an outside company perform the grounding study for us. They do all the tests necessary and come up with a recommended scheme, including: what size ground conductor for the main grid, how many ground rods, ground rod and grid spacing, etc. From there we take the information and put it on our drawings. We then add any take-offs for our equipment.
There were a couple of issues discussed in one of our meetings, and since I am pretty new to grounding, it wasn't clear to me.
One being this: we require the main ground grid to be 2ft below finished grade. That's spec., so that's ok with me. But they mentioned that any grounding of the upper elevations should have risers from the main ground grid below, a ground loop(3ft from wall), and take-offs for equipment. This is according to a first-line supervisor. I didn't agree. Previously I had been providing a grid for each elevation.
question: why shouldn't we have a ground grid on any/all elevations? Wouldn't that be more safe? Is it a waste of copper?
RE: Grounding training
Either way is fine, you get what you pay for. I am not too knowledgeable on ground grids of upper elevations but I believe they use the rebar in the floors that already exists and then preferably a ring around the perimiter as you mentioned.
There are some ground grid gurus in here, I am sure you will a better answer shortly.

If you're looking for design guidance, MIL-HDBK-1012/1 is free for download, and a very good design guide for electronic facilities. The DoD has other documents for substations, power transmission and grounding/bonding, too. They may not necessarily be directly applicable to you, but they almost invariably represent good engineering practice and are a good reference for where the code books let off.

When you are speaking of upper elevations, could you be more specific? From the mention of risers and takeoffs for equipment, I would have thought that you were talking about a substation structure, except I don't understand what you mean by a grid for each elevation, and the other posts assume that you are talking about some sort of building.
