Model for radio interference produced by corona pulses on a. c. lines

A model is proposed for radio interference produced by pulsed corona on a.c. lines. This model uses pulse shapes which agree with experimental observations, and it incroporates the timing information forced on the corona by a sinusoidally varying voltage. For applied voltages ranging from the onset Voltage to a level just below the spark voltage, predictions are given of the mean corona current and the spectral density. The effect of the alternating line voltage on the spectral density is indicated through an example.
