Electrical Transmission Line Design References 3

[hhhii]

I am designing a 138 kV electrical trasmision line. I am following RUS Guide lines so I started of with the RUS "Design Manual for High Voltage Transmission Lines". However, this manual can be vague. I am looking for any references to guide me through the process of designing. I can find formulas, however, I need to know what how many items to calculate and where to use them.

So any refernce matertials (books, websites, periodicals, etc.) that you feel will help me would be appreciated.

Aluminum Electrical Conductors Handbook published by Aluminum Association. You may find it too vague as well, but realize that nobody is likely to publish a step-by-step guide to babysit you through the process. You should have a senior engineer available to mentor you; if not, better hope your liability insurance is paid up.

One other reference I thought of: the legendary Westinghouse Transmission and Distribution Reference Book. Still published by ABB, although a bit dated, but again it won't give you a cookie cutter method.

Usually if you find the right senior engineer to guide you, you will find they already have the right reference materials as well. Amazing what those old geezers accumulate over the years!

Get the Electrical Engineers Handbook, fourteenth
edition.

Also, check out

http://www.alexanderpublications.com

They have some good T & D stuff.

You should probably get software for what
you are doing. Go to:

They have a good design guide with their PLS-CADD.

The PLS-CADD several years ago cost $10,000....but well
worth the cost.

Also a company called Linesoft has software.

Lastly, for sagging/tension data you should
get software entitled SAG10, to obtain the
correct values for the particular conductor.

All

Thanks for the help. I am looking into all of the references. I do have PLS-CADD/Lite. It seems to do all that SAG10 does at 1/4 the cost. I am looking into PLS-CADD full version at $10,000.

redtrumpet...your comment about babysitty was a little harsh, especially for a forum that offers help.

"I am looking for any references to guide me through the process of designing."

It's a fine line between guiding and babysitting. I really don't mean to be nasty, but in a previous post you seemed a bit baffled as to how to determine critical design inputs for your sag-tension software program. Now it seems you have realized your software isn't going to do the design on its own, and you actually have to learn something. This would be all good and fine if this was a small distribution line and you could compare your design with published utility standards to see if it passed the reasonableness test.

But come on man, this is a 138 kV transmission line!

I would hope the process of designing should be half-assed clear to anyone designing a 138 kV transmission line. My impression is that you are at best naive and at worst incompetent for the task at hand.

hhiii,

You might want to hire someone to develop the terrain
or profile drawings for you before you begin.

Do you have the easements and/or ROW's obtained?

Don't do any layouts yet until these have been obtained.

Also, I can remember when I first apprenticed under
an older 'stressed out' engineer when we were designing
controls for a fossil-fired power plant in Minnesota.
He used the term 'babysit' frequently, but as I later
learned, it was a figure of speach, which I learned to
accept. Can't you imagine what (names) the soldiers were calling each other during WWII, but somehow, everyone got along and won the war. Learn to forgive and forget.

Peace on earth to everyone!
