Corona loss in bundled conductors

AI Thread Summary
Calculating corona power loss for bundled conductors involves understanding various methods and formulas, which are often not freely available online. Increasing the distance between conductors generally reduces corona loss, but the impact of changing distances within the same bundle is less clear. The discussion highlights that while corona can damage air and insulators, bundled conductors are designed to minimize such losses. Users are encouraged to provide specific details about their conductor geometry and operating conditions for more tailored advice. Accessing technical journals through university libraries may provide additional insights into the topic.

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?

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
