In this paper, the power transformer monitoring system (PTMS), which uses expert database to detect failures and hybrid wavelet-fourier transform (HWFT) to compress data is introduced. The HWFT takes advantage of both: discrete wavelet transform (DWT) and discrete cosine transform (DCT), to compress data. It has been proved that HWFT outperforms DCT and DWT, which are used in JPEG and JPEG2000 compression standards, in terms of compression ratio while preserves the same accuracy of decompressed signal.
