Corona Loss for 132 kV Single CKT Line.

12/05/2013 11:49 PM

hi,

what is the value of corona loss for 132 kV line (in terms of kW/km/phase) line that acts as threshold and above that the corona loss becomes high and is considered unpermissible. I need it for line design.

Regs,

sks

sks, since you took Lyn's bait it's a pretty good indication that this is beyond your capabilities. As far as the loss that's something that the company you're consulting for should tell you, what's acceptable in one ambient condition may be unacceptable under another.

Time to be forthright with your client and suggest that he engage the services of a firm specializing in this type of work, any error on your part will be extremely expensive and time consuming to correct later.

I may have transposed the numbers. Are you north, or south, of the equator?

You can talk posting anonymously sauravbabu!

Do you actually work in the electrical industry or are you just a student asking homework questions expressed in a dishonest way to make it look like you work in the industry!

Either way on behalf of the actual Power and Transmission Engineers here, based on your post history we are ethically required to NOT answer your questions (see CR4 post guidelines and copy of Ethics for Engineers course paper for explanations as to why). The same way we are ethically responsible on this forum for answering medical surgery procedure performing questions or questions on how to launder money or build bombs.

So stop asking, do your own homework or hire a competent Engineer before you get someone killed.

Here's my 2¢ on the subject. Lets just hope he finds another occupation away from anything to do with engineering!

I bid 27..!..

You're an AP so as far as everyone is concerned here you and your question aren't worth the electrons we waste messing with you..!..

Use a screen name we can track from thread to thread and post to post and the odds are you will get far more relevant answers..!..

Nope, it's 42.

It's the answer to everything.
Including homework.
