RE: Busbar Calculation
Can you help me with the voltage, amp/hours and physical dimensions. Best price would be a bonus.
Seriously, what is your application? Are these bus bars for a substation, an MCC, a PDC, or transit supply?

Rigid-bus structures for outdoor and indoor, air insulated, and alternating current substations are covered. Portions of this guide are also applicable to strain bus structures or direct current substations, or both. Ampacity, radio influence, vibration, and forces due to gravity, wind, fault cur-rent, and thermal expansion are considered. Design criteria for conductor and insulator strength calculations are included.

But it's to expensive for me :(
Maybe you know a free paper or other solution , i don't know...
Thanks

I've to calculate a tubular cooper busbar for a outdoor station (europe standards).
I need a technical guide (free) that covers this subject.
Anyone?

RE: Busbar Calculation
if you ask specific questions you will more than likely get specific answers. Waross's original response, albeit tinged with sarcasm was very valid. So far you've asked vague generic questions. Don't be surprised to receive responses in the same vain. If you provide more basic detail as to the application, electrical data, diagram etc it is very likely you will get the response you require. There's nothing engineers like more than getting to grips with a situation they can visualise in their own minds. I for one would have lost the will to live long before I'd finished typing in instructions on how to design a substation from the ground up.

Broad, general questions about things like this can make people very nervous. This site can never be an adequate tutorial on substation design, but if you have a have specific question with what you've tried to solve it and why your solutions didn't work you will find very helpful, detailed responses.
RE: Busbar Calculation
I apologise for the time that I made to you waste. I am not upsetting any more. Thank you all.

You might want to have a look at the following:
htt
This used to be available as a proper book, now just as a download. There are some useful equations if you are working from first principles.
If this is a design for a service environment then the advice from the others is spot on: buy the standard. Your client will (should) demand that the design conforms with the standard, so you will need to refer to it.

My copy of the CDA book is from the late fifties or early sixties. I'm not sure why they stopped publishing it but it is a shame. I much prefer a reference book to be something I keep on a shelf. There are some marvellous old photos of switchgear: one is a 250V 40,000A DC circuit breaker. That's 40kA thermal rating!
