Recommendations for software

    I am looking to buy some software at work. I would like to do

    1. short circuit studies
    2. coordination studies

    and MAYBE in the future (but maybe not)

    3. voltage drop
    4. load flow (hopefully allowing for pf correction caps to be applied)
    5. harmonic load flow (hopefully allowing for pf / filtering L & C to be
    applied)
    6. ground grid design (enter soil layers, conductor & rod layouts, etc.,
    calculate Rg, step & touch potentials, etc.)

    and finally,

    7. some function you think is a good one that I didn't include above

    Money is an object, to some extent. If anyone can recommend some
    software(s) they like for the above functions, please include a guess at a
    ballpark cost with it, if you can. I know some packages offer basics for
    one price, and for increasing price you get more functionality. Something
    like that would be fine, too. I do not work at/for a utility, it is
    consulting, largely in the commercial and institutional building sector.

    I used to use a lot of EDSA. Very expensive and it seemed a bit of a
    clunker. I like to copy and paste text (i.e. coordination study breaker
    settings, short circuit study fault levels, etc.) and graphics (i.e.
    time-current curves, harmonic waveforms, etc.) from these programs into,
    say, Word, so that I can make a decent looking report, all in one file. It
    would be nice if the software I find allows for this.

    If there is software freely available for any of the above, of course I
    would like to hear about that, too.

    Thanks to any and all for their help,

    My opinions based on use of several of the major packages:

    For utility transmission & distribution systems -- Aspen One-liner. It has
    the overwhelming market share amongst utilities and is well supported and
    documented. Only negative about it is that it doesn't support low-voltage
    (below 480V) industrial protection devices very well. It also doesn't have
    the complete set of functions that you specify. http://www/aspeninc.com

    For industrial, generation, and small utility applciations -- SKM Powertools
    for Windows. A quality product with a long history. I believe that SKM is
    the oldest of the manufacturers of this type of software. Their first
    packages were written for Alpha machines. Full suite of capabilities (for a
    price of course) and great support.

    before you jump off and buy the software, are you an licensed electrical
    engineer or with a PE?
    I am not and have run into areas that need a pro to decide what to do. I am
    comfortable with doing some calculations to get to an "go-no go" situation.
    It is the ones that do not fall into these categories easily that are the
    ones that need an experienced person.
    My old company had a product called Pow-R-Designer, check Eaton Electric.
    There are a lot of choices out there good luck on your search.
     
  5. You can get the software in any college (mine: www.teiher.gr )and the former
    www.teikoz.gr but its homepage sucks.Literally:eek:nly engineers know these
    things (and the professors that teach these engineers).

    Thank you for the help, and the advice. Let's just say that if I were a
    professional engineer, I'd be disinclined to say so because who knows what
    liability issues could arise. Even if not now, what about in the future.
    I'll check Cutler for that program.

    Thanks for your response. I was unable to search those links very well as I
    run out of English pages right away. If you know of any software there that
    is in English, could I get you to post links to some of those pages for me?

    Looks like they disco'ed Pow-r Designer but they are offering a free version
    of some new program, for Cutler devices. Thanks for the tip.

  9. I thought they had an english version.Better ask a local engineer, or attend
    classes better in ee (if you have money and can get in a ee course in a
    local college).I don't know any ready-to-use software, as told these
    knowledge is engineers' secret.
