Effective competition for local monopoly cable systems would seem to offer a natural solution to nagging problems widely attributed to the cable industry, such as high prices and poor service. In regulatory and legislative proceedings leading up to the Cable Television Consumer Protection and Competition Act of 1992,(note 1) however, potential or existing competitors to local cable systems comp...

We have proposed and demonstrated a Michelson interferometer-based fiber sensor for detecting acoustic emission generated from the partial discharge (PD) of the accessories of a high-voltage cable system. The developed sensor head is integrated with a compact and relatively high sensitivity cylindrical elastomer. Such a sensor has a broadband frequency response and a relatively high sensitivity...

Seafloor observation system using the underwater cable is one of the most reliable ways to provide high-speed data transmission and continuous power feeding to underwater devices. Recent evolution in the optical submarine cable and Internet technology make it possible to develop a versatile scientific submarine cable network. IEEE OES (Institute of Electrical and Electronics Engineers, Oceanic ...

The introduction of distributed energy resources (DER) is leading to significant changes in the way in which power systems are planned, operated and maintained. DER includes many different types of technology, ranging from producers of electricity such as microgeneration units to consumers of electricity such as heat pumps and electric vehicles. High penetrations of these new technologies are i...

Clinically, cardiac fibrillation caused by spiral and turbulent waves can be terminated by globally resetting electric activity in cardiac tissues with a single high-voltage electric shock, but it is usually associated with severe side effects. Presently, a promising alternative uses wave emission from heterogeneities induced by a sequence of low-voltage uniform electric field pulses. Neverthel...

Steel cables are widely used in cable-stayed bridges, suspension bridges and so on. It is important to test them periodically for their safe operation. The cable tension is one of the key testing parameters. Magnetoelastic methods are usually adopted to measure the cable tension due to their non-contact features. However, it is difficult to install the exciting and receiving encircling coil on ...

Abstract The cable routing problem is the task of designing minimum‐cost electrical network between turbines offshore wind farms while satisfying several constraints. It contributes to decreasing energy costs, favoring green transition. This paper focuses on balanced routing, studying both branched and radial topology. First, we propose a visibility graph route cables around obstacles boundarie...

It is well known that existence and accumulation of space charge within the insulating material poses threat to the reliability in the operation of dc power cables. When the cables are loaded under high voltage direct current (HVDC), temperature gradient is developed across the insulation material. In this paper, commercial ac XLPE power cables were used under an application voltage of 80 kV dc...

Cable theory has been developed over the last decade, usually assuming that the extracellular space around membranes is a perfect resistor. However, extracellular media may display more complex electrical properties due to various phenomena, such as polarization, ionic diffusion, or capacitive effects, but their impact on cable properties is not known. In this paper, we generalize cable theory ...

Electricity demand has been increasing due to the increase of population and industries. Hence it is very important to feed the demand with quality of generation. Improvement of power quality is the greater concern in advanced power system element, it is essential to congregate the need of energy by employ the renewable energy generating sources like pv, fuel cell, biomass, wind, etc and utiliz...
