Q1. What is Corona Loss? At what voltage it happens? What is Critical Disruptive Voltage?
Ans. 
Corona loss is the power loss in transmission lines due to ionization of air around the conductors. It occurs at high voltages. Critical disruptive voltage is the voltage at which corona loss starts.
• Corona loss is caused by the ionization of air around high voltage conductors

• It occurs at voltages typically above 220 kV

• Corona loss increases with increasing voltage and frequency

• Critical disruptive voltage is the voltage ...read more
