fault current calculation software
(OP)
I'm looking for software for fault current or short circuit calculations.
This software is to allow the correct selection of the AIC rating for
electrical panels.

RE: fault current calculation software
The electric utility you are connected to typically supplies the Available Short Circuit Current upon request.
If you are connected to a generator of some sort, the manufacturer specifications should list the AIC required.

Otherwise, try contacting some of the fuse manufacturers (i.e. Gould/Ferraz, Bussmann, Littelfuse).

1. SKM, Inc. software called Dapper, A-Fault, Captor, etc.
www.skm.com
2. EDSA Power System Analysis Software by EDSA Microcorporation
www.edsa.com
3. Operation Technology, Inc. software called Etap
www.etap.com
All the above software are good, depending on your application and industry, and shall suffice for your needs.
RE: fault current calculation software
I Suggest to use the ETAP software which is one of the most familiar s/w in this field.

Be warned this is a basic calculation that needs information to fill in the blanks and does not add motor contribution to the calculated fault. It will get you to an AIC as quickly as any I have used and is betteer than using only the Utility contribution.

You can download it free from

Ben:

///These parameters are good at the upper tiers of the power distribution system. Any power distribution downstream may need to be refined to establish lower fault levels and not to pay for unnecessarily expensive electrical equipment because of excessive short circuit currents or faults. Also, at some points, there may be motors that contribute to the short circuit levels.\\\
If you are connected to a generator of some sort, the manufacturer specifications should list the AIC required.
///Again, my above comment applies. Also, one must account for motor contributions of short circuit currents to the faults.\\\

Go to the ETAP web site and request the demo CD, you have no chance of getting the package for "Free"

ETAP is the software you are looking for to run SC analysis :)
RE: fault current calculation software
You can contact ETAP at 949-462-0100 for a free demo. I have used the software on a number of projects and is worth it if the project can justify the cost. Being modular you dont have to buy everything!

Can anybody tell from where i can down load a software which is same as ETAP for free.

Not quite ETAP, but something to start with.

are comprehensive software tools for the electrical power system modeling, analysis, computations, etc. They are fairly complex and expensive to develop and are not for free beside limited demo periods with some restrictions.
There may be proprietary expertise programmed in the software, e.g. algorithms.
The manufacturers, e.g. Siemens, Cutler-Hammer, General Electric offer their software packages with libraries including their equipment only.
