Advantages and
Disadvantages of Corona
The various advantages of corona effect
are,
1. Due to corona, the air surrounding
the conductor is ionised and becomes conducting. This increases the virtual
diameter of the corona.
2. Corona reduces the effects produced
by the surges and conductor is saved from possibility of lightning. It acts as
a safety device.
The various disadvantages of corona are,
1. The corona power loss is the biggest
disadvantage which reduce the transmission efficiency.
2. The third harmonic components
produced due to corona makes the current nonsinusoidal. This increases the
corona loss.
3. The ozone gas formed due to corona
chemically reacts with the conductor and can cause corrosion.
