Transmission Line Impedance- Calc

[spc300]

I need to quickly determine the line impedance for several different designs. can anyone direct me to or provide a calculation tool (i.e. Mcad, Xcel etc.)THX?

I use Aspen Line Constants.

I appreciate the response, however the Aspen program is not available, hence the request for other readily availble tool(s).

What do mean that it’s not available? Maybe now it’s not available until Monday, but “not available?”

Putting all those equations into something is a lot of work. Been there, done that, not interested in giving it away.

Any good power systems textbook like William D. Stevenson plus Excel or Mathcad. Plus a lot of work like David said.

I use the Westinghouse T&D book for the hand calculations I have done in the past.
Not exactly fun, but once you put them in a spreadsheet, not so bad.
