The problem of electric field grading in cable components, having both theoretical and technological implications, can be framed in more general topic of field control in HV equipment. A solution may be obtained by two possible approaches: using geometric field control [11, 13, 14, 15, 17, 18], in which the field distribution depends on the arrangement of main and auxiliary electrodes or using ...

The transmission of the electric power to shore and concepts for the electrical system of offshore wind farms are evaluated with respect to selection of a cable. Necessity of use of a shunt by an AC cable connection to shore is addressed, Consequences of the use of a higher insulation of cables, use of three single core cables in triangular and linear configuration is compared in the paper.

Applications of on-line PD spot testing and monitoring for in service power cables are presented. The motivation and advantages of the on-line approach to the cable insulation assessment are covered. The different aspects of PD testing are discussed: detection, location and continuous monitoring. The test techniques for different types of transmission and distribution cable circuit are shown wi...

In this paper robust PID control of fully-constrained cable driven parallel manipulators with elastic cables is studied in detail. In dynamic analysis, it is assumed that the dominant dynamics of cable can be approximated by linear axial spring. To develop the idea of control for cable robots with elastic cables, a robust PID control for cable driven robots with ideal rigid cables is firstly de...

Cable structure is a major component of long-span bridges, such as cable-stayed and suspension bridges, and it transfers the main loads of bridges to the pylons. As these cable structures are exposed to continuous external loads, such as vehicle and wind loads, vibration control and continuous monitoring of the cable are required. In this study, an electromagnetic (EM) damper was designed and f...

This study reports an adaptation of a parametric echosounder system using 15 kHz as secondary frequency to investigate the angular response of sub-bottom backscatter strength of layered mud, providing a new method for enhanced acoustic detection of buried targets. Adaptions to achieve both vertical (0°) and non-vertical inclination (1– 15°, 30°, 45° and 60°) comprise mechanical tilting of the a...
