Low‐frequency noise removal and acoustic spectral distribution assessment method for high‐voltage power transformers with varying service lifetimes

Abstract The acoustic signals of power transformers serve as key indicators for assessing operational statuses and detecting internal mechanical issues. However, low‐frequency noise, such as fan noise, often obscures critical features. This study introduces an adaptive low‐frequency denoising algori...
