大気中直流針端コロナ放電による超短波帯雑音特性

抄録

Pulsating corona discharges on high voltage transmission lines are the major sources of radio and television interference. In consideration of multiple corona discharges it seems that noise frequency spectrum and level would be affected to a great extent by the waveform, pulse ampulitude and repetition rate of the corona pulse. This paper describes the experimental results with the various curvature needle electrodes used as models of line conductor surfaces in order to clarify the fundamental effect of DC corona pulse on the noise over the VHF band.
