What is corona power loss in transmission line hvdc?
Transmission lines while there is ceramic insulators providing separation to the phases will have a corona if the insulators are dirty providing small current leakage ionizing the air around it therefore corona effect. Read More »

What is Corona power loss in transmission line?
Corona Fields arround a transmission line is the high electric field caused by the transmission line causing the surrounding air to ionise and conduct electricity. As this ionisation requires a current to maintain, this causes a loss associ... Read More »

As electrical transmission lines span hundreds of miles, there will be some load loss incurred. The longer the line, the more electricity will be lost to the resistance inherent in the line material. Joule's Law states that energy losses ar...

For a long transmission line, the lower losses and reduced construction cost of a DC line can offset the additional cost of converter stations at each end. Also, at high AC voltages, significant amounts of energy are lost due to corona disc...

It is necessary because lightning can destroy whole phase conductors. Lightning has energy of 1MHp. So much high energy if falls on transmission line will not even destroy it but all of the distribution systems too. The reason that lightnin...

Theoretically either increase the voltage or reduce the resistance. Both of these have downsides so power companies try to find a happy medium. Higher voltages become more expensive to manage, transformers, insulators etc. Lower resistance ...

You could replace the conductor, but at the present time that is prohibitively expensive. The most economical conductor is aluminum cable. Losses can be reduced with effective insulators, of course, which is also already being done. Transfo...
