Overhead Cable Ampacity

[bgalloway]

I would like to find an affordable, yet easy to use with WIN95, program to calculate the ampacity of various overhead conductors - AAAC, ACSR, etc. - for various temperatures and altitudes. Can anyone recommend such a program?
Thanks!

 

If you are looking for a program that is designed for bare overhead distribution conductors, there is a basic program included with IEEE 738, but it is DOS based.

I found one that requires you to have AutoCAD at:

I guess it is a module that you use with AutoCAD.

There is one other program I found out there called ThermCap. Their website is located at

http://www.thermcap.com

and it says it uses the IEEE 738 methodology. This one looks to be a stand-alone program for windows operating systems.
Hope this helps...

Try

http://WWW.Powerline.com

they have software called PLS-CADD/LOADS that performs thermal ratings of OH line conductors. Also the old Westinghouse T&D Manual goes through calculations using Schurig and Frick formulas to determine thermal rating of bare OH lines.
