De-Noise of the High Frequency Corona Current with Wavelet Analysis Method

Abstract:

In order to analyze wide frequency band corona current characteristics of the UHV bundled conductors, a corona current measurement system is developed. The corona current signal is transmitted to the lower computer through the wireless network. And the current signal collected in this way is safe and reliable. The de-noise method with wavelet analysis is introduced and compared with some common used methods. The result of the de-noising analysis of the wide frequency band corona currents of bundled conductors in the corona cage shows that the wavelet analysis method could be used to de-noise high frequency corona current in the corona cage, and the de-noising effect is apparent.
