HTS Fault Current Limiters
By: Leanne Naidoo & Pranesh Sarjoodei
Introduction



Fault Current ,Circuit Breakers
Fault currents are unanticipated power disturbances in the utility grid caused by lightning etc
This causes circuit breakers to open and close. Circuit breaker will remain open in wait for repair crew.
Until the power is restored, an outage occurs.
In today s electricity dependant economy, significant hardships and economic losses occur during the outages

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

kaizen case study ppt in wires and cables industry
The wire and cable industry has moved from being a small industry 20 years back to a very large industry over the last decade. Although it is a volume-driven product, it has a lot of quality and technical particulars. Over a period of time, the industry has moved from the unorganised to the organised sector. However, about 35% of this industry is still in the unorganised sector. Requirements like brand and quality perception are key in this Rs 15,000 crore industry. The wire and cables industr ....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

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
