In order to extract the millivolt range partial discharge(PD) signals drown in the harsh electromagnetic interference for HV power cables, this paper presents a novel antiinterference method, based on fast fourier transform autothresholding method, 1-D discrete wavelet thresholding method and three phase amplitude and arrive-time difference method. This method is examined and proved to be effec...

In order to access the severity of degradation in a water tree affected cable, it is necessary to obtain a physical representation of the insulation. This is especially the case when trying to determine the risk of failure of the cable, or the remaining life, which is dependant on the length of the longest water tree in the insulation. Generally, there has not been a large effort found in publi...

An increasing problem of ageing cable insulation requires a development of certain methods for online conditioning and offline assessment. Thus, Partial Discharge (PD) monitoring is the most effective technique for assessment of insulation condition. PD monitoring and analysis has become imperative for utilities as well as for equipment manufacturers as it causes deterioration of insulation sys...

The "loopless antenna" is an interventional MRI detector consisting of a tuned coaxial cable and an extended inner conductor or "whip". A limitation is the poor sensitivity afforded at, and immediately proximal to, its distal end, which is exacerbated by the extended whip length when the whip is uniformly insulated. It is shown here that tapered insulation dramatically improves the distal sensi...
