Download or read book Determination of Hotspot Location and Conductor Temperatures from Spare Duct Temperatures in an Underground Installation written by Aman Sharma and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work a comparison has been made between the predictions from the models using both the present theory for the underground cable temperature prediction and the CYMCAP application and the field measurements to determine which, if any, models are capable of predicting the temperature and hotspot locations in an installation where the power cable is not embedded with the optical fibers and, therefore, where the cable temperatures must be inferred from the temperature measurements made in nearby spare ducts. The temperature measurements were collected from the underground 69 kV cable at the Brandow-Pickrell installation, which is a part of Salt River Project's power sub-transmission system. The model development and the results are explained in detail. Results from the model developed have been compared and the factors affecting the cable temperature are highlighted. Once the models were developed, it was observed that the earth surface temperature above the installation, solar radiation and other external factors such as underlying water lines, drain pipes, etc. play a key role in heating up or cooling down the power cables. It was also determined that the hotspot location in the power cable in the main duct was the same as the hotspot location in the spare duct inside the same installation. It was also observed that the CYMCAP model had its limitations when the earth surface temperature variations were modeled in the software as the software only allows the earth's ambient temperature to be modeled as a constant; further, results from the MATLAB model were more in line with the present theory of underground power cable temperature prediction. However, simulation results from both the MATLAB and CYMCAP model showed deviation from the measured data. It was also observed that the spare duct temperatures in this particular underground installation seemed to be affected by external factors such as solar radiation, underlying water lines, gas lines etc. which cannot be modeled in CYMCAP.

Download or read book An Assessment of the Concept of Critical Temperature in Underground Power Cable Design written by and published by . This book was released on 1991 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: The performance of underground power cables is critically affected by the thermal properties of backfill soil around the cable. The possibility of thermal drying of soil around a power cable complicates the thermal design process. According to the European design model, the cable ampacity is a function of the critical temperature of the backfill soil. At present, this approach is used in the thermal design of cables carrying continuous load, and the critical temperature values are assumed to be unique to a given soil type. This report gives the results of a laboratory study designed and conducted to determine the critical temperature of a uniform sand.

Download or read book Thermal Instability of Underground Power Cables written by and published by . This book was released on 1989 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The performance of underground power cables is critically affected by the thermal properties of the backfill around the cable. When the heat transfer process induces rapid thermal drying of the backfill soil causing the cable temperature to rise rapidly, the cable system is said to be thermally unstable, or results in thermal runaway. This report reviews the mechanism of thermal runaway and proposes a rational basis for identifying the potential for thermal instability in various types of soils. The relevance of the factors selected for the identification system is substantiated by the results of a parametric study.

This book was released on 2016-01-07 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The successful transmission of electrical power beneath the surface of the earth depends on a number of factors including ambient temperature, sheath bonding, cable laying depth, and especially the formation of dry zones around underground cables. Environmental Impacts on Underground Power Distribution studies the factors which affect the maximum current rating of subterranean power cables as well as various methods to maximize electrical current transmission. Focusing on the latest tools, methodologies, and research in the field, this publication is designed for use by electrical engineers, academicians, researchers, and upper-level students.

Download or read book Electrical Power Cable Engineering, Third Edition written by William A. Thue and published by CRC Press. This book was released on 2011-12-13 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fully updated, Electrical Power Cable Engineering, Third Edition again concentrates on the remarkably complex design, application, and preparation methods required to terminate and splice cables. This latest addition to the CRC Press Power Engineering series covers cutting-edge methods for design, manufacture, installation, operation, and maintenance of reliable power cable systems. It is based largely on feedback from experienced university lecturers who have taught courses on these very concepts. The book emphasizes methods to optimize vital design and installation of power cables used in the interrelated fields of electrical, mechanical, and, to some extent, civil engineering. An in-depth exploration of power cable characteristics and applications, it illustrates the many factors that can hinder real-world cable performance. Content focuses on low and medium voltages, considering that these are used for the majority of cables in service globally. This edition also details techniques for testing shielded power cable systems in the field, demonstrating how conductor material size and design depend on ampacity, voltage regulation, and other factors. Covering everything from manufacturing to testing, this resource will benefit: Cable engineers and technicians (working for investor-owned utilities, rural electric cooperatives, and industrial manufacturers) who need to improve their oversight and understanding of power cables Universities that offer electrical power courses Professionals who must master new power cable terminology, engineering characteristics, and background information that will aid them in their decision making responsibilities The author is a life fellow of the IEEE and one of the original developers of industry standards for cables and accessories. To simplify field fundamentals and techniques for less experienced readers, his book contains new, updated, and expanded chapters and an extensive glossary, in addition to useful references, tables, equations, and photographs. More experienced engineers will appreciate the book’s invaluable updates on the emerging materials, products, and concepts driving their dynamic field.
