High Voltage Engineering - J R Lucas, 2001 150 In the case of power line suspension insulators, it is possible that breakdown or flash over would occur due to high frequency over voltages produced by faults or switching operations in the line. A complete quantitative description of the topics in high voltage engineering is difficult because of the statistical nature of the electrical breakdown phenomena in insulators. With this in mind, this book has been written to provide a basic treatment of high voltage engineering qualitatively and, wherever necessary, quantitatively.
