Corona Effect & list of all Hospitals

Corona Effect

Definition: The phenomenon of ionisation of surrounding air around the conductor due to which luminous glow with hissing noise is rise is known as the corona effect.

Air acts as a dielectric medium between the transmission lines. In other words, it is an insulator between the current carrying conductors. 

If the voltage induces between the conductor is of alternating nature then the charging current flows between the conductors. And this charging conductor increases the voltage of the transmission line.

The electric field intensity also increases because of the charging current.
If the intensity of the electric field is less than 30kV, the current induces between the conductor is neglected
