Corona loss in bundled conductors

Click For Summary

Discussion Overview

The discussion revolves around the calculation of corona power loss in bundled conductors, exploring various methods and factors that influence these losses. Participants seek formulas and theoretical insights while addressing practical implications and challenges in accessing relevant literature.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant requests formulas for calculating corona power loss in bundled conductors.
  • Another participant mentions the difficulty in finding accessible articles on corona power loss, noting that various methods exist for these calculations.
  • A participant expresses curiosity about the effects of changing the distance between conductors within the same bundle on corona loss, acknowledging that increased spacing generally reduces loss.
  • One participant shares a link to a PDF document, possibly containing relevant information.
  • Another participant argues that there should not be any corona loss in bundled conductors, suggesting that corona primarily affects air and insulators, which are resistant to such effects.
  • A participant reiterates the request for formulas and asks for specific details regarding the geometry of the conductors, voltage levels, and frequency.

Areas of Agreement / Disagreement

Participants express differing views on the existence and implications of corona loss in bundled conductors, with some asserting it is negligible while others seek to understand its calculation and effects more deeply. The discussion remains unresolved with multiple competing perspectives.

Contextual Notes

Participants have not reached consensus on the impact of corona loss in bundled conductors, and there are unresolved questions regarding the specific conditions under which these calculations apply.

can anyone tell me that how to calculate corona power loss for bundled conductor? I need formulae of it.
 
Engineering news on Phys.org
I googled corona power loss, and got lots of hits. Unfortunately, almost all of them are for abstracts of papers that you would need to purchase to download. But if you look at the journals that they were published in, you may have those journals available for check-out at your University's technical library. Here's the hit list for you to look over:

It appears that there are a number of different methods to do these calculations.
 
I've also searched, but i couldn't find any free article.
As we know if we increase the distance between comductors, corona loss decreases, but i want to know that what will happen if v change the distance between conductor in same bundle?
 
check this pdf document http://www.tripledoubleyou.com/zaius/damper.pdf .

Corona creates something like acid and if there is any corona, most solid insulators will fail.
Corona in air only damages the air and insulators. The air is replaced with other air and the material used for insulators is resistant to corona.

What is your geometry (number of conductors, insulation, spacing), voltage levels, and frequency?
