Abstract A better understanding of the interaction between three phases is required when developing superconducting cables for high voltage AC systems. With a particular focus on energy losses real power transmission cables, in this paper we utilize so-called H-formulation Maxwell equations to devise 2D model triaxial cables. The major aim comprehend and reproduce experimental observations repo...

As the submarine cable industry has moved from copper to optical fibers for signal transmission, the cables have become increasingly smaller and the amount of ferromagnetic material in them has been drastically reduced. Many festooned cables are being constructed so that they contain no copper or other means for electrical signal transmission in them at all. These cables have become increasingl...

Partial Discharge is a phenomenon that indicates cables or joints deterioration in an electrical transmission or distribution system. Mechanical damages, voids or contamination in the insulation of cables or joints may contribute to the degradation thus emission of PD is present. The electromagnetic pulses emitted may represent the condition of the insulation. Current PD detector designed using...

electrical resistivity survey is used to explore subsurface layers in hydrology, geology, mining, geotechnical and environmental investigations. the resistivity measurements are normally made by injecting current into the ground through two current electrodes, and measuring the resulting voltage difference at two potential electrodes. electrical resistivity is a function of injection current, m...
