Current-Transformer Saturation Detection Using Savitzky-Golay Filter

Current-Transformer Saturation Detection Using Savitzky-Golay Filter

A new application of the Savitzky-Golay (SG) filters in current-transformer saturation detection is proposed. The ability of the SG filters to handle noisy signals improves the robustness of the detection process in the presence of noise while requiring only low computational effort.
