The advantage
of corona is that, it results into,
Increase in transients
Corrosion of conductor
Increase in effective conductor size
Hissing noise
Increase in effective conductor size
The
advantages of corona power loss are –
(1) The
maximum electrostatic stress reduced.
(2)
Probability of flash over is reduced.
(3) System
performance is improved.
(4) Virtual
increase in conductor diameter
