Research on Frequency Characteristics of Signal Radiated from Corona Discharge
In the shielded room, the effect of different factors, which includes different polarity of potential, direction of polarization of antenna, receiving distance, the shape of discharging needle, temperature and humidity etc., on the spectrum of signal radiated from corona discharge. According to the experiment, it concludes that the waveform of signal radiated from corona discharge has a steep rising edge; the spectrum of signal radiated from corona discharge is continual spectrum, which frequency range is from 20MHz to 100MHz; when the polarity is different, the waveform of signal radiated from corona discharge is different, and the amplitude of signal of positive corona is higher than of negative corona; the politicization mode of fields radiated from corona discharge is vertical; the intensity of fields radiated from corona discharge is inversely proportional to the receiving distance; the relative humidity is different, the amplitude of signal is different, the higher the relative humidity is, the higher the amplitude is.
