An introduction to high-voltage experimental technique

This comprehensive guide covers essential principles and practices in high-voltage experimental techniques. It begins with the generation and measurement of high alternating and direct voltages, including voltage multiplier circuits, followed by impulse voltages and currents. Non-destructive testing methods are also discussed. The layout and operation of high-voltage laboratories are addressed, detailing dimensions, technical equipment, and safety measures such as fencing, earthing, and shielding. The guide outlines circuits and construction elements necessary for high-voltage experiments. A series of practical experiments are presented, including those on alternating and direct voltages, impulse voltages, electric fields, and the properties of insulating materials. Additional experiments investigate partial discharges, gas breakdown, impulse voltage measuring techniques, transformer tests, internal overvoltages, travelling waves, and impulse currents and arcs. The appendices provide crucial safety regulations for conducting high-voltage experiments, calculations for short-circuit impedance in transformers, single-stage impulse voltage circuits, impedance of plane conductors, and statistical evaluation of measured results. This resource serves as a valuable reference for both practitioners and researchers in the field of high-voltage engineering.
