Electrical Short Circuit Sotware? 2

[ahazlewood]

Does anyone know of a GOOD software package for short circuit calculations? Our company bought EDSA some time ago (hey, the sales-guy made it look so friendly)and we have since found that it has a pathetic "users manual" thus requiring several thousands of extra dollars for training.

I have used about 6 different types over the years, and they all have one problem in common. Without training, you can waste a lot of time doing things the long way or the wrong way or (usually) both. But changing from one to another is not something to be approached without considering the hidden costs. These are mainly the data conversion costs (I'm talking utility usage here, rather than consultants or those doing one-off studies). You've just got your models going, or have just started getting the models, data gathering, databases etc sorted out, then you have to do it all again for the next great new program. Aaargh!

But what is definitely worthwhile is getting input from all users before you buy the new one. I have been lumbered with using a package that is great for the distribution planning boys, but is a complete dog for my transmission protection studies. (Gues who specified and bought it). The interfaces to the corporate databases are all set in concrete, so I just have to make do with fixes and work-arounds because the funds aren't there to support two sets.

DO NOT listen to those who reckon the program they are using is the bee's knees, unless you are sure their needs are the same as yours. And even then, be sure you know what compromises they are accepting, because they all require them.

Some things I would look for in a program would be:
1] can it do everything all users need
2] can it do most of what all users want
3] will it run on my platform (Windows, Linux, Unix, MacOS or whatever)
4] does it have restrictive licencing requirements, dongles, etc
5] can I get my system data into the database and maintain it?
6] can I convert my old data to the new format easily?
7] can I get data in and out (copy and paste, etc) using standard cross-application functions (eg OLE, ActiveX controls etc in Windows)
8] is it compatible with the network my machines are on?

Good luck!

Mr. Stepe, I was wondering if you know of the Fluor view on that, or if that is known? I can see that they have certainly empowered the world of engineering. Such a good firm, that even gives their competitors such powerful capabilities, not only thinking of themselves, and until now, never taking credit for that, is very high in my view.
