This software is most useful in our applications like analysis of LV panels and Modular panels structural mechanical stresses and internal electric-thermal stresses etc. Pls, find it and send the material booklet in PDF format.

    There’s AutoCAD plug-in “MeteorSpec” that calculates the specifications of cables.
    Program has a Data Library where all the data about the cables you use are saved.
    Program can generate reports as specifications (summarized lengths per cable type) or as explications (list of all cable with detailed information).

    The program can be configured to use in any field of design where calculation of total lengths and total areas is needed.

    Look at Autodesk Exchange apps. https://apps.exchange.autodesk.com/ACD/en/Detail/Index?id=appstore.exchange.autodesk.com:meteorspectrial_windows32and64:en

    Thank you very much for your most informative news.
    My problem is, the home electrical bill/energy consumption/electrical load calculator did not work better for me.
    Eg. I worked out the load current / power consumed by 10 x CFL bulbs 15W and got 470.68 A / 150kW (according to the calculator), and thus compelled me to install 600A Incoming ELCB in my residence?
    Please take a look and advice.

I shall suggest that some information may be given on Electrical Engineering Safety not general but specific in various opeartions of Electrical Engineering Systems, also Safety Softwares are required to be provided for free downloading. Hope the Portal will consider my suggestions. Thanks

    Dear Webmaster and Engineering Team;

    I am an Electrical Senior Engineer with +9 years Experience who work in Schneider Electric Iran. I just express my appreciation for your well-organized web site which in most cases provide appropriate technical data. However in some case it could be improved with presenting more practical data, links, etc which are considered in daily routine design for electrical engineers. nevertheless I believe that good effort shall salute and you deserve that when spreading knowledge freely and helping Electrical Engineer community to boost their qualities. such web sites shall be supported and encouraged to follow their services.

    I wish all the best for all of you.
    Good Luck

    Hello everyone.

    I’m pretty new over here and I need some help.
    On the project that I’m working I need to design some time current curves for specific relays. The time current curves must have more than two characteristics(Overload and short circuit) and I couldn’t find any software for designing such specific curves(I’ll give an eg to be more specific: I need a curve where the first drop is at 1500 A in 5 sec, the second is at 3300 A in 2 sec a third one at 10 000 A in 0.1 sec). The only one that I found useful is CYMTCC software. In the older version of CYMTCC(4.5) I can’t design only with two characteristics. In the new version, which is 5.0 I can add a new characteristic but on the trial version I can not export, save or print the project. And I can not pay some hundred dollars only for some of this curves.
    So please, if you can, tell me some software where I can design this curves.
    Thanks a lot,
    Sergiu.

Still have a lot to learn though but I will certainly visit this website often and I would certainly recommend it to others! *Thumbs up*
