line conductance

Dielectric strength is around 30 kV/cm peak

According to Peek’s formula, power losses due to corona depends by the network frequency

Under abnormal weather conditions, corona losses decrease

Peterson’s formula can replace Peek’s formula when the corona losses increase

Bundle arrangements provide benefit against corona effect

Corona effect can give some advantages in case of transient events

The corona loss is observed to be a function of frequency. Losses, therefore, increase with increased frequency. Since there is no frequency in DC transmission, corona loss is less compared to AC one.

The lower the pressure and the higher the temperature the higher the corona losses

The effect of corona can be reduced by either increasing the size of the conductor or the space between them. Therefore, whatever increases the radius of the conductor, decreases the corona losses

For ball-and-socket insulator, the power loss at 10kV is about 10kW

Critical Disruptive Voltage is the minimum voltage at which ionization takes place

Line conductance is associated to the reactive power produced by an electric line
