ADSS Cables on EHV, HV, MV Transmission Lines

The installation of fiber-optic cables on transmission towers that support EHV, HV, MV transmission lines provides an effective communications system on electric networks. Electric utilities have used fiber-optic cables for several years to provide a communications page link between neighboring substations or between substations and the control desk. It opens new perspectives for the future to create all optical Internet and other c ....etc

ABSTRACT
Urban electrical power systems with steep demand increase need easily located solutions with short lead time from decision to transmission. While AC cable solutions can offer sufficient power ratings, the problems of load controllability and short circuit power increase with every added circuit. These problems may be countered with Voltage Source Converter (VSC) based technology using Cables for transmission, such as HVDC Light. This technology offers up to 500 MW per station with small footprint, ideal for in feed to city centers. ....etc

Abstract

This paper proposes a new soft-switched continuousconduction- mode (CCM) boost converter suitable for high-power applications such as power factor correction, hybrid electric vehicles, and fuel cell power conversion systems. The proposed converter achieves zero-voltage-switched (ZVS) turn-on of active switches in CCM and zero-current-switched turn-off of diodes leading to negligible reverse-recovery loss. The components voltage ratings and energy volumes of passive components of the proposed converter are greatly reduced c ....etc

Effect of HVAC System on Neighbouring Pipelines and
Communication Cables

A. Abu-Siada, M. Bahram
Curtin University of Technology, Australia

Abstract
Sharing of common corridors between power lines, pipelines and telecommunication lines is becoming a familiar scene. High levels of voltages can be induced in services which run in parallel or in close vicinity of high voltage AC transmission lines, in particular during a fault on the transmission line. These hazardous voltages can affect people coming into contact ....etc

HTS wire
Using high-temperature superconductors cables with higher transmission capacities, smaller cross sections and lower transmission losses can be built.
Commercial quantities of HTS wire based on BSCCO(Bismuth strontium calcium copper oxide) are now available at around five times the price of the equivalent copper conductor BSCCO wire requires an expensive batch production process and relatively high quantities of silver. YBCO coated conductors is being manufactured in in a semi-continuous process. Manufacturers are claiming th ....etc

underground cables seminar report

Abstract

Underground cables are the electric power transmission cables. Because of their reliability on transmitting, they used in congested urban areas and in thick population areas, where overhead transmission is dangerous. Underground cables have low maintenance cost, less chances of faults, smaller voltage drop. In recent improvements in the design and manufacture have led to development of cables suitable for use at high voltages. Electric power can be transmitted or distributed either by overhead system ....etc
