Available in PDF, EPUB and Kindle. Book excerpt: The mechanical impedance of a foundation depends, in part, on the characteristics of the column attached to it. For this reason it is important to have a technique to find that mechanical impedance with the column in place; this requirement rules out direct measurement with an impedance head. This study was made to determine the usefulness of a transient loading technique for measuring the mechanical impedance of a complex termination. The method determines the impedance at the end of an elastic bar from the Fourier Transforms of pulse shapes in the bar. Experimental results for a simple termination show that this technique can be used to measure the impedance of a lumped parameter system. However, comparison between transient loading measurements and direct measurements with an impedance head for a more complex termination show that not enough frequency information can be obtained to determine its impedance accurately enough.

Download or read book High Impulse Voltage and Current Measurement Techniques written by Klaus Schon and published by Springer Science & Business Media. This book was released on 2013-07-03 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Equipment to be installed in electric power-transmission and distribution systems must pass acceptance tests with standardized high-voltage or high-current test impulses which simulate the stress on the insulation caused by external lightning discharges and switching operations in the grid. High impulse voltages and currents are also used in many other fields of science and engineering for various applications. Therefore, precise impulse-measurement techniques are necessary, either to prevent an over- or understressing of the insulation or to guarantee the effectiveness and quality of the application. The target audience primarily comprises engineers and technicians but the book may also be beneficial for graduate students of high-voltage engineering and electrical power supply systems.

Download or read book High Frequency Characterization of Electronic Packaging written by Luc Martens and published by Springer Science & Business Media. This book was released on 2013-11-27 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-Frequency Characterization of Electronic Packaging will be of interest to researchers and designers of high-frequency electronic packaging. Understanding high-frequency behavior of packaging is of growing importance due to higher clock-speeds in computers and higher data transmission rates in broadband telecommunication systems. Basic knowledge of the high-frequency behavior of packaging and interconnects is, therefore, indispensable for the design of future telecommunication and computer systems. High-Frequency Characterization of Electronic Packaging gives the reader an insight into how high-frequency characterization of electronic packaging should be done and describes the problems that have to be tackled, especially in performing accurate measurements on modern IC-packages and in determination of circuit models. High-Frequency Characterization of Electronic Packaging is conceived as a comprehensive guide for the start of research and to help in performing high-frequency measurements. Important notions in high- frequency characterization such as S-parameters, calibration, probing, de-embedding and measurement-based modeling are explained. The described techniques are illustrated with several up-to-date examples.
