A cable configuration technique for the balance of current distribution in parallel-connected single-core cables is proposed. Based on the mutual inductance theorem, a closed form solution for the calculation of current distributions in parallel-connected cables is first derived. To compare the performances of different cable configurations, two indices are introduced, one for the power losses ...

In order to carry out the simulation of the electrical noise, a pulse generator with fast rise time is needed. For this reason, the pulse generator using a coaxial cable is usually used. The pulse generator consists of a DC power supply, a charging resistor, a coaxial cable, a relay, and a terminator. Even the same voltage as charge voltage was outputted when the termination of the impedance wa...

The KM3NeT EU-funded consortium, pursuing a cubic kilometre scale neutrino telescope in the Mediterranean Sea, is developing technical solutions for the construction of this challenging project, to be realized several kilometres below the sea level. In this framework a proposed DC/DC power system has been designed, maximizing reliability and minimizing difficulties and expensive underwater acti...

A cable operator chooses to bundle or provide programs à la carte by striking a balance between maximizing total surplus and minimizing transfer payments to program providers. We show, using general demand and cost functions, that a cable operator’s decision to bundle maximizes total producer surplus if the cable operator’s bargaining power is sufficiently high, and that a cable operator in a w...

This paper demonstrates a new type of interconnects to fulfill the primary function of axons: transmitting electrical signals over long distances and at high speeds. The interconnect, which we call ‘‘ionic cable’’, uses ions to transmit signals, and is built entirely with soft, elastic materials—elastomers and gels. The ionic cable is highly transparent, and remains functioning after being stre...

Subsurface power grids constitute one of the largest copper stocks in many industrialized cities. Over time, parts and zones of these systems have been continuously disconnected and abandoned, resulting in the emergence of urban infrastructure ores. This study aims to assess how current conditions and practices influence economic and environmental motives of cable recovery from such power grids...

In high voltage power cable system, partial discharge (PD) is a common phenomenon which reflects the degradation of insulation. When partial discharge happens inside the cable, leakage current will flow through the grounded conductor. To couple the partial discharge current, one feasible and effective method is placing a clamp-on high frequency current transformer around the grounded strap. In ...

Series elastic actuators (SEA) are playing an increasingly important role in the fields of physical human-robot interaction. This paper focuses on the modeling and control of a cable-driven SEA. First, the scheme of the cable-driven SEA has been proposed, and a velocity controlled DC motor has been used as its power source. Based on this, the model of the cable-driven SEA has been built up. Fur...
