Corona loss in bundled conductors

Click For Summary
SUMMARY

The discussion centers on calculating corona power loss in bundled conductors, highlighting the need for specific formulas. Users express difficulty in finding accessible resources, as many articles require purchase. It is established that increasing the distance between conductors reduces corona loss, while variations in spacing within the same bundle also affect loss calculations. The conversation emphasizes the importance of understanding conductor geometry, insulation, voltage levels, and frequency for accurate assessments.

PREREQUISITES
  • Understanding of corona discharge phenomena in electrical engineering
  • Familiarity with bundled conductor configurations and their characteristics
  • Knowledge of electrical insulation materials and their properties
  • Basic principles of electrical power transmission and loss calculations
NEXT STEPS
  • Research the formulae for calculating corona power loss in bundled conductors
  • Explore the impact of conductor spacing on corona loss in bundled configurations
  • Investigate the effects of voltage levels and frequency on corona discharge
  • Review technical papers on corona effects and mitigation strategies in power systems
USEFUL FOR

Electrical engineers, power transmission specialists, and researchers focused on optimizing the performance and reliability of bundled conductors in high-voltage applications.

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?

There should not be any corona loss in bundled conductors.
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?
