| Abstract: | Based on variety of fractal dimension scale and principle of self-similarity, this paper presents a new digital analysis system for PD signal recognizing and processing. Application of fractal character to calculate and detect PD pulse signal of XLPE power cable using high frequency wide-band electromagnetic coupling is able to restrain noise interference and pick up PD signal key eigenvalue effectively. The technique for on-line detection of partial discharge in XLPE power cable has been improved in this paper. |
