The paper proposes a structural model of decision support system for controlling cable insulation continuous vulcanization line. proposed is based on mathematical the technological process, database, and mode correction algorithm. DSS will make it possible to quickly develop new regime in case using materials or structures, as well correct current unplanned changes during production process. co...

Partial discharge (PD) measurements are universally accepted as a technique giving some indication of the state of the insulation in high-voltage apparatus. Cable end users are keen to adopt online PD monitoring during commissioning of systems. However, because of noisy environments and the problems of interference the conventional methods are difficult to implement. As a consequence, ultra-hig...

While the signal quality of recording neural electrodes is observed to degrade over time, the degradation mechanisms are complex and less easily observable. Recording microelectrodes failures are attributed to different biological factors such as tissue encapsulation, immune response, and disruption of blood-brain barrier (BBB) and non-biological factors such as strain due to micromotion, insul...

This paper presents a substantiation of an approach for direct measurements dielectric dissipation factor layers insulation between the conductors three-core power cables. Proposed is based on grounding inspecteddielectric layer through sufficiently low electrical resistance. The results carried out analysis, which was taking into consideration presence numerous parasitic parameters tested due ...

The role of a series of functionalized graphene additives in power cable insulation in suppressing the growth of electrical treeing and preventing the degradation of the polymer matrix has been investigated by density functional theory calculations. Bader charge analysis indicates that pristine, doped or defect graphene could effectively capture hot electrons to block their attack on cross-link...

Crosslinked polyethylene (XLPE) has become the globally preferred insulation for power cables, both for distribution and transmission system applications. This insulation system provides cost efficiency in operation and procurement, as well as lower environmental and maintenance requirements when compared to older impregnated paper systems. The purpose of this paper is to outline some of the de...

Partial discharge (P.D.) in micro cavities in the insulation of H.V. power cables drastically affect the performance, the field distribution and hence the rating of these cables. It is well known that, P.D. deteriorates power cables and lead to its complete failure. This has adverse effects on the reliability and maintainability of power supply, which affects directly the production of industrial

Transvenous extraction of Riata lead could be a challenging procedure due to insulation failure and conductor cables' externalization through the eroded outer insulation. In this case, a complete lead extraction was achieved through a combined LASER and femoral approach because of the massive conductors' externalization.

The paper presents the research on space charge distribution under different polarities in full size cross-linked polyethylene power cables using the pulsed electro-acoustic technique. Under both positive and negative voltage space charge distributions possess about the same profiles but opposite polarities. Similar phenomenon had been reported previously in plaque samples and was termed as “mi...

damping of a full-scale cable with a pair of passive–on magnetorheological (mr) dampers was tested. a cable of 215.58m long with the first mode frequency of 0.658hz was tensioned horizontally in cable prefabrication factory. two mr dampers were attached to the cable in an angle in the plane perpendicularly to the cable axis in 5m length from the cable anchorage. the applied voltage level was 0v...
