Extra high voltage ac transmission engineering



It is nearly a decade since the publication of the Second Edition of this text-reference book
authored by me and needs a revision. No significant developments have taken place in the
basic theory and principles of e.h.v. transmission engineering, except for increase in
transmission-voltage levels, cables, magnitudes of power-handling capabilities, as well as of
course the cost of equipment and lines.
But two problems that need mentioni ....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

INTRODUCTION:
The main function of any transmission system is transfer power from a place to
another place or from a network to another network..
Any transmission system consists terminal substations,transmission lines and
intermediate substations.
The increasing need of transmission of greater power led to continuous
increase in the transmission voltages.By the urge Extra High Voltage tran-
smission is introduced.
HISTORY:
In 1886 in Great Barrington, Massachusetts, a 1 kV alternating curre ....etc

Abstract
The term high voltage characterizes electrical circuits in which the voltage used is the cause of particular safety concerns and insulation requirements. High voltage is used in electrical power distribution, in cathode ray tubes, to generate X-rays and particle beams, to demonstrate arcing, for ignition, in photomultiplier tubes, and high power amplifier vacuum tubes and other industrial and scientific applications.

Electricity often travels over very long distances to reach urban load centres. For example, the distance between Baie-James region where water from the Grande Rivi re ends up after driving the turbines in eight power stations and Montr al is about 1,000 kilometres as the crow flies. However, the farther electricity must travel, the greater the risk that part of it will be lost on the way. Since utilities invest heavily in the high-volume transmission of power over long distances, they take special steps to limit these transmission losses.W ....etc

Measurement and simulation of the electric field of high voltage
suspension insulators

Vassiliki T. Kontargyri, Ioannis F. Gonos*,y and Ioannis A. Stathopulos


INTRODUCTION
The insulator strings, which are used for the suspension of overhead transmission lines, constitute one of the most important parts of
the transmission lines as they used to give support to electrical conductors and shield them from ground or other conductors as well
as they provide the necessary mechanical supports for the tra ....etc
