Analysis of traveling waves in underground cables
Abstract
The form of overvoltage in underground cables for a wave with a vertical front and a falling crest is analyzed. The derived expression enables an estimate of the voltage in the cable as a function of time for any length of cable and duration of the overvoltage wave. The shorter the cable the more accurate the calculation. Figures show overvoltages in cables between two power lines and between a power line and a transformer (assuming certain wave resistances).
