摘要

Measurement of partial discharge (PD) has been used to assess the condition of insulation material used in electric power equipment. Analysis of the electromagnetic (EM) waves emitted from PD is useful from the viewpoint of noncontact diagnosis because PD emits wideband EM waves. The EM waves emitted from PD is numerically visualized using the constrained interpolation profile (CIP) method and the time delay between the EM waves measured at different positions is estimated using the cross-correlation (CC) method based on the in-place fast Haar wavelet transform (IP-FHWT).
