Implementation of an On-Line PD Measurement System Using HFCT

Authors: F. Haghjoo, M. Sarlak, S.M. Shahrtash


In order to perform on-line measuring and detection of PD signals, a total solution composing of an HFCT, A/D converter and a complete software package is proposed. The software package includes compensation of HFCT contribution, filtering and noise reduction using wavelet transform and soft calibration routines. The results have shown good performance and high accuracy.
