Consider the
following statements regarding corona :
1. It causes
radio interference.
2. It
attenuates lighting surges.
3. It causes
power loss.
4. It is more
prevalent in the middle conductor of a transmission line employing flat
conductor configuration.
Which of the
above statements are correct ?
1,2 and 3 only
1,2 and 4
only
1,2, 3 and 4
3 and 4 only
1,2, 3 and 4
Corona effect in an electrical discharge brought on by the ionization of a fluid such as air surrounding a conductor which is electrically charged.
Corona causes
radio interference, power loss, reduces the magnitude of lightings &
switching and it is more prevalent in the middle conductor in a flat conductor
configuration.
