A water bridge refers to an experimental "flexible cable" made up of pure de-ionized water, which can hang across two supports maintained with a sufficiently large voltage difference. The resulting electric fields within the de-ionized water flexible cable maintain a tension that sustains the water against the downward force of gravity. A detailed calculation of the water bridge tension will be...

The conductivity mismatch in the composite insulation of high voltage direct current (HVDC) cable accessories causes electric field distribution distortion and even insulation breakdown. Therefore, a liquid silicone rubber (LSR) filled with SiC nanoparticles is prepared for the insulation of cable accessories. The micro-morphology of the SiC/LSR nanocomposites is observed by scanning electron m...

The superconductivity was discovered in 1911. In the same year, Sumitomo Electric Wire & Cable Works was established (Foundation was in 1897 as Sumitomo Copper Rolling Works), and laid the first Japan-made high-voltage underground cables. In 2011, we will celebrate the centennial anniversary of the discovery of superconductivity, and a high-temperature superconducting (HTS) power cable will be ...

This study examines conductive noise in long distance cables in a subsea environment. The conductive noise was caused by impedance mismatch between cables and appeared in the form of transient voltages. In particular, it is important to analyze the characteristics of transient voltages for different subsea temperature changes. To analyze the transient voltages, the effects of L, R, and C for di...

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.

We study the formation and propagation of a normal zone in Rutherford-type superconducting cables. We use a rectangular conductor model to account for the electric current redistribution process between the multifilamentary strands in the presence of a normal zone. We obtain and integrate numerically the diffusion equations for the temperature and the current density distributions. Our simulati...

Neurons generate magnetic fields which can be recorded with macroscopic techniques such as magnetoencephalography. The theory that accounts for the genesis of neuronal magnetic fields involves dendritic cable structures in homogeneous resistive extracellular media. Here we generalize this model by considering dendritic cables in extracellular media with arbitrarily complex electric properties. ...

An investigation of the current distribution in a 3-phase triaxial superconducting cable was conducted to study the phase imbalance under steady-state operation and to assist in the construction of a transient model to study operational impacts in a power grid. The triaxial cable consisted of three superconducting concentric phases inside a copper shield, with each phase composed of multiple la...

In the area of mobility (transport), great efforts are being made to optimize means transport. While reducing their mass main goal is maintain or even improve performance Additive manufacturing allows production very complex geometric shapes products that cannot be by traditional processes; therefore it has become one significant tools in design modern vehicles parts. manufacturing, combined wi...
