Relevant Characteristics Of Power Lines Passing Through Urban Areas

Relevant Characteristics of Power Lines Passing through Urban Areas covers a variety of problems in electric-power delivery that were considered for a long time in professional and scientific circles unsolvable. Taking into account the influence of all surrounding metal installations on the relevant characteristics of HV and EHV lines passing through urban and/or suburban areas, this reference provides safe and economical solutions on how to check and achieve prescribed safety conditions, determine the dangerous and harmful inductive influence of HV and EHV lines, enable compensation of deficiency for all unknowns, understand relevant data concerning surrounding metal installations, and more. This book is necessary for properly dimensioning cable systems, considering the existing underground structures near substations and providing engineers with the necessary information they need to design normal operations and determine fault events. Includes methodologies that enable solutions for several types of problems in electric-power delivery that were previously unsolvable Defines specific field measurements by guiding the development of corresponding analytical procedures Showcases a clear scope for the application for HV and EHV distribution networks

This book gives the solution for a long known and, in the professional and scientific circles, not seldom mentioned problem - how one can determine mutual, inductive influence between an electric power line and metal installations surrounding this line in urban and/or suburban areas. The method presented in this book enables the compensation of the objective deficiency of the necessary data about the surrounding metal installations through the field measurements. The calculative part of the method is based on introduction of a fictitious conductor which is equivalent, from the standpoint of the inductive effects, to all actually existing surrounding metal installations. Physical appearance of this conductor is assumed to be a cylinder enveloping all conductors of the considered power line along its entire length. The book is assigned for the use of professionals involved in the design and exploitation of distribution network, but also is recommended to the academic people: professors, postgraduates, graduated and students of electrical engineering.

Practical Methods for Analysis and Design of HV Installation Grounding Systems gives readers a basic understanding of the modeling characteristics of the major components of a complex grounding system. One by one, the author develops and analyzes each component as a standalone element, but then puts them together, considering their mutual disposition, or so-called proximity effect. This is the first book to enable the making and analysis of the most complex grounding systems that are typical for HV substations located in urban areas that uses relatively simple mathematical operations instead of modern computers. Since the presented methods enable problem-solving for more complex issues than the ones solved using National, IEC and/or IEEE standards, this book can be considered as an appendix to these standards. Develops general equations of lumped parameter ladder circuits Includes the analytical expression for determination of ground fault current distribution for a fault anywhere along a cable line Presents measurement and analytical methods for the determination of actual ground fault current distribution for high-voltage substations located in urban areas Provides the analytical procedure for the determination of the critical ground fault position for faults appearing in outgoing transmission lines Defines testing procedure for the correct evaluation of grounding systems of substations located in urban areas

"Akashvani" (English) is a programme journal of ALL INDIA RADIO, it was formerly known as The Indian Listener. It used to serve the listener as a bradshaw of broadcasting ,and give listener the useful information in an interesting manner about programmes, who writes them, take part in them and produce them along with photographs of performing artists. It also contains the information of major changes in the policy and service of the organisation. The Indian Listener (fortnightly programme journal of AIR in English) published by The Indian State Broadcasting Service, Bombay, started on 22 December, 1935 and was the successor to the Indian Radio Times in English, which was published beginning in July 16 of 1927. From 22 August ,1937 onwards, it used to published by All India Radio, New Delhi. From 1950,it was turned into a weekly journal. Later, The Indian listener became "Akashvani" (English ) w.e.f. January 5, 1958. It was made fortnightly journal again w.e.f July 1,1983.

The transport sector consists of different modes of transport, each serving a growing demand for transporting people and goods. This (growing) demand on the one hand, needs expanding the systems’ capacity, and on the other hand, increasing the corresponding economic efficiency, effectiveness, and environmental and social friendliness. This implies development of a ‘greener’, i.e. a more sustainable transport sector. The book describes the current and prospective state of the art analytical modelling, conceptual planning, and multi-criteria evaluation of the selected cases of transport systems operated by different transport modes such as road, rail, sea, air, and intermodal. As such, the book is unique in addressing these three important aspects of dealing with transport systems before implementation of their particular components means by the selected cases. It will be particularly useful for readers from the academia and the professionals from the transport sector.
