Corona loss is less when the shape of the conductor is?
Circular
Why armature core is laminated in dc machine?
to reduce the eddy current loss in the machine
How do you reduce the Power dissipation?
Answer for mechanical systems:Use oil or grease to reduce friction!Answer for electrical systems:Making the voltage as high as possible is a good way to reduce power loss.ExplanationThe voltage drop along a conductor is proportional to the resistance and to the current carried. (V=IxR) So, for a given quantity of Power (W=VxI), if the voltage is made as high as possible there will be less current flowing and therefore less power loss.
Advantage of double circuit distribution line?
1. initial cost is low 2. reduce the loss by reducing the resistance
Transformer Output power less than input power?
A: Absolutely a power transfer will have an internal loss of IR . for a power transformer the loss can be as much of 20% or more if other magnetics are involved like iron screw holding the lamination together. Usually brass is used to reduce that loss.
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
Why do cold storage rooms have thick walls made of hollow bricks?
Hollow bricks are used as air is a good insulator. Thick walls are used to reduce heat loss to the surroundings as the brick is also a poor conductor of heat. (although not as much effective as air)
What frequency corona loss is more?
frequency is directly propotional to corona loss... so higher the freq the corona also high..
Why Does filling a cavity with foam reduce heat loss even further?
Because foam has many little air pockets, which reduce heat loss. Also, air is an insulator which means it is a poor conductor. Hope that helped!
What is corona effect in electrical?
When the distance between two conductors is more than that of the diameter and the potential difference is increased beyond the certain limit in such a way so that a glow ( seems like violet and shine ) is produced around the conductor and also noise is produced. This kind of effect called the Corona Effect in power systems. As the potential difference is increased, Corona Effect is also increased, and due to Corona Effect, Power loss in power system and disturbance in the nearer communication line is also increased.
How does a plastic box help to reduce heat loss?
Plastic is an insulator therefore it is a poor conductor of heat. A plastic box will therefore be able to keep a lot of heat on the inside.
How does plastic box help to reduce heat loss?
Plastic is an insulator therefore it is a poor conductor of heat. A plastic box will therefore be able to keep a lot of heat on the inside.
How do mutual funds reduce the risk of loss?
Mutual fund do not reduce the risk of 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.
What help the fish body to reduce water loss?
The scales on the fish body helps it to reduce water loss.
Explain the term corona in transmission line.?
At very high voltages, corona becomes an issue, such as in high power transmission. In effect, if there are any "sharp points", square corners, etc., electrons will tend to build up and this build up begins to damage the structure. this is why in very high voltage subs, you will see rings used instead of bolts or hooks (easiest to see at the top of poles).
