High Impulse Voltage and Current Measurement Techniques

This book examines principal generator circuits for generating high-voltage and high-current impulses as well as measuring systems and their calibration according to IEC 60060 and IEC 62475 methods of estimating uncertainties of measurement.

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.
