Transmission Line and cable parameter program 1

[ePOWEReng]

Hello. Does anyone know of a free transmission line and cable parameter program that is avaliable for excel, or can be run through a website, or possibly a stand-alone freeware program? I have a bunch of mathCAD worksheets but sometimes I have a hard time getting use a machines that have MathCAD and the MathCAD sheets are generally not very scalable (i.e. changing a .mcd file from deriving and single three phase structure to a three phase structure mutually coupled to another three phase structure takes some time).

You can get ATP for free (

http://www.emtp.org)

and it has line constants calculation modules, but it may be like swatting flies with a sledge hammer.

davidbeach, thanks for the feedback. I am familar with the line constants program in ATP it is a little cumbersome....but probably what I'll end up using.

Below is a link with solution example in MathCad with good algorithms applicable to multiple lines.

The last edition of the American Public Power Association magazine has an excel spreadsheet.
