A synthetic noise suppressing algorithm for partial discharge signals of generators

Abstract: Analysis of Partial Discharge (PD) signal is one of the most effective and commonly used techniques to estimate a condition of the winding insulation of generators and requires highly precise analysis. To satisfy this requirement, various noise suppressing methods have been proposed and developed to eliminate external noises those were measured with PD signals. However, some external noises those cannot be removed by conventional noise suppressing methods have been come out and decreased the reliability of the… Show more

“…In 2009, Y.W. Youn et al proposed a comprehensive noise suppression method for the noise in partial discharge signals that cannot eliminate traditional noise suppression methods [65]. It consists of two noise suppression methods: the adjacent phase induction noise suppressing technique and the adaptive noise suppression technique, which executes the two noise suppression methods sequentially on the collected signal data.…”
