When Corona Discharge occurs it forms ozone and nitrogen oxides. These combined with moisture to prduce nitric acid, which is destructive to most dielectrics and certain metallic compositions, resulting in corrosion. In addition, the high energy in some discharges results in mechanical, electrical, and thermal damage. SC

Best dielectric material for corona discharge?
Mica sheet
What is the visible discharge of electricity surrounding a charged conductor when its potential exceeds the critical value at which the surrounding air is ionized?
Corona.
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).
Why 400kVA and above the transmission line have bundled conductor?
To reduce the electric field intensity at the surface of the conductor which can lead to corona discharge and insulation breakdown. By using bundled conductors, the electric field is distributed between the four (in the case of 400-kV lines) conductors, thus reducing the field intensity per conductor.
Tears in the sun's corona provide an exit for?
solar winds
What is the definition of a corona discharge?
A corona discharge is the ionization of the surrounding atmosphere after an electrical discharge. This can usually be seen as a glowing of a different color near high voltage conductor points.
Can you explain the corona discharge method of generating ozone?
Yes.
Best dielectric material for corona discharge?
Mica sheet
Chief justice Renato corona will be convicted by the senate?
Yes, he should be convicted because of the strong evidences against him!
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
How does a van Der graft generator work?
It is based on the principle of static induction and action of points (corona discharge)
What is the visible discharge of electricity surrounding a charged conductor when its potential exceeds the critical value at which the surrounding air is ionized?
Corona.
What has the author Marie Farnsworth written?
Marie Farnsworth has written: 'The equilibrium of carbon dioxide with carbon monoxide and oxygen in the corona discharge ..' -- subject(s): Chemical equilibrium, Corona (Electricity), Electric discharges through gases
How are you producing ozone at ground level?
Ozone is produced in laboratories by corona discharge method. It can also be produced by treating oxygen with UV radaitions.
What are the different types of electrostatic discharge?
There are three main types of electrostatic discharge (ESD): direct discharge, indirect discharge, and field-induced discharge. Direct discharge occurs when a charged object comes into direct contact with another object. Indirect discharge happens when the charged object interacts with another object that is not in direct contact. Field-induced discharge occurs when the electric field between objects causes a discharge without direct contact.
On what date did Christopher Columbus report a glowing object rising from the sea and rising into the air?
The light was reported by Columbus in his journal on October 11, 1492, which is believed to have been Saint Elmo's Fire (a corona discharge: an electrical discharge accompanied by ionization of surrounding atmosphere).
