Dear Colleagues,

The substantial growth of cable HV interconnections has prompted researchers to investigate the degradation factors of the dielectric materials used in these systems. Dielectrics in AC and DC cables experience ageing phenomena that are worth of investigation due to the high costs associated to the failures of such infrastructures. In particular, HVDC systems early diagnosis poses a great challenge due to the lack of standardization and consolidated technologies for testing. As is well known, the space charge accumulation and the partial discharge (PD) phenomena play an important role in DC cables’ dielectrics ageing. For this reason, several measurement techniques were developed in order to monitor these phenomena. For instance, the Pulsed Electro Acoustic (PEA) method is one of the main techniques used to measure the space charge. Despite its wide use, the cited technique is destructive, and several technical issues are still present during testing, e.g., the attenuation of the charge signals and the presence of reflected signals in the output charge profile. Therefore, solutions regarding existing space charge measurement (like the Thermal Step Method or PEA) to improve the output charge profile and avoid cables destruction are strongly encouraged. Moreover, the measurement of the PD phenomenon under distorted waveforms is considered of great interest. This Special Issue welcomes studies on the state of the art of new methodologies for cable fault and pre-fault analysis, PD analysis in HVDC cables, innovative cables design, and possible changes of cables structures with the aim to improve and facilitate PEA and PD measurements. Apart from original research articles related to the topic, studies on the effect of the polarity reversal and transient overvoltage phenomena in the lifetime of power cables are also welcome. Finally, due to their ease of use, wireless AC PD detection methods, as well as fault detection and localization approaches, will be considered of interest.
