Why there is no corona in DC transmission?
Bcoz, corona effect is only possible in high voltage AC supply due to the frequency. That is, the frequency and the HT voltage causes the arc b/w 2 conductors.so , here the air is act as the arc transmitting medium.we called it as Corona. It is highly impossible in DC bcoz of no frequency.
Corona loss is less when the shape of the conductor is?
Circular
What are the advantages of corona loss?
-it prevents conductor from electrical surges -it increases virtual diameter hence conductor can carry more current -corona discharge is used in photo copier and laser printers
Effect of frequency in power loss?
Power loss in a system is directly proportional to frequency; as frequency increases, power loss also increases due to factors such as skin effect and dielectric losses. Higher frequency signals encounter increased resistance in conductors, leading to more power dissipation as heat. This effect is important to consider in high-frequency applications to ensure efficient and reliable operation.
How Hollow conductor is used to reduce corona loss how does it reduce the loss?
to have large diameter without increasing its weight.
A sensorineural hearing loss is most often associated with loss of hearing sensitivity in which of the frequency ranges?
high frequency sounds
Is controlling frequency and severity of loss events can reduce risks?
Yes, controlling frequency and severity of losses reduces overall loss.
Can controlling frequency and severity of loss events reduce risks?
Yes, controlling frequency and severity of losses reduces overall loss.
What is corona power loss in transmission line hvdc?
A: 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.
Why uplink frequency is kept higher than downlink freqquency in satellite communication?
due to path loss : higher is the frequency higher is the patrh loss
What part of the sun is seen during a solar eclipse?
The corona.
Where can one find Corona Florist online?
