corona loss advantage and disadvantages

 advantage of corona loss

  • due to corona , the air surrounding  the conductor is ionized and becomes conducting. this increases  the virtual diameter of the conductor.
  • corona reduces the effect produced by the surges and conductor is saved from possibility . it acts as a safety device.

   disadvantage of corona loss

  • it reduces the transmission efficiency.
  • the third harmonic components produced due to corona makes the current non-sinusoidal. this increases the corona loss.

  • the ozone gas formed due to corona chemically reacts with the conductor and can cause corrosion.                                                                                                                                                            corona power loss formula
