Data Preprocessing of On-line Monitoring tanδ Based on Mathematical Morphology Filter

Wang Nan et al  
The principle of mathematical morphology is briefly introduced in this paper. Then a novel approach based on mathematical filter to preprocess on-line monitoring tanS data is presented. With moving structure element, the singular points among the data can be detected and smoothed effectively. The physical meaning of this approach is clear, and it is easy to be realized. Problems of its application in preprocessing tanS data are pointed out too. Finally, analysis results of practical data have verified its effectiveness.
