Bundle Conductors Corona Current Harmonic Wave Measurement

Abstract:

In order to research high level harmonic wave of six bundle conductors corona current, a measurement system was developed, and a series of wave data was obtained. Corona current is one of important corona characteristic research contents. The corona current measurement system can be used to measure the wide frequency band corona current. Six-bundle conductors was tested, and corona current was obtained. And the current signal collected in this way is safe and reliable. To research the six-bundle conductors’ corona current characteristic, conductor corona current harmonic wave was analyzed, by advanced Hanning windowed interpolation FFT algorithm was adopted. Corona current harmonic characteristics before and after corona onset were compared. Research results show that, after corona onset, corona current odd harmonic increases in evidence, and even-order harmonic increase less relatively. Triple-frequency harmonics and quintuple harmonics increase obviously very much.
