Discussion of "A novel fault detection technique of high impedance arcing faults in transmission lines using the wavelet transform"

The authors comment on the paper by C.-H. Kim et al. (see ibid., vol.17, p.921-9, 2002). They ask the authors to describe the circumstances for 154 kV system arcing faults. They also comment on the fault inception angle, wavelet selection, and the advantages of the wavelet transform in relation to its use.
