Beschreibung
A guide to the physics of Dynamic Temperature Sensing (DTS) measurements including practical information about procedures and applications
Distributed Fiber Sensing and Dynamic Ratings of Power Cable offers a comprehensive review of the physics of dynamic temperature sensing measurements (DTS), examines its functioning, and explores possible applications. The expert authors describe the available fiber optic cables, their construction, and methods of installation. The book also includes a discussion on the variety of testing methods with information on the advantages and disadvantages of each.
The book reviews the application of the DTS systems in a utility environment, and highlights the possible placement of the fiber optic cable. The authors offer a detailed explanation of the cable ampacity (current rating) calculations and examines how the measured fiber temperature is used to obtain the dynamic cable rating information in real time. In addition, the book details the leading RTTR suppliers, including the verification methods they used before their products come to market. Information on future applications of the DTS technology in other aspects of power system operation is also discussed. This important book:
* Explains the required calibration procedures and utility performance tests needed after the installation of a DTS system
* Includes information on the various practical aspects of communicating measured and computed quantities to the transmission system operator
* Reviews possible applications of the technology to fault location, vibration monitoring, and general surveying of land and submarine cable routes
Written for cable engineers and manufacturers, Distributed Fiber Sensing and Dynamic Ratings of Power Cable is an authoritative guide to the physics of DTS measurements and contains information about costs, installation procedures, maintenance, and various applications.
