Modeling in PSCAD / EMTDS of traveling waves in a single-wire power transmission line is considered. Traveling waves of the terrestrial mode are generated at the beginning and in the middle of the line in different ways. The effects of dispersion, w hich lead to the dependence of the recording time of a traveling wave on the value of the registration threshold and on the distance traveled, are considered. The term of instantaneous and average speed is introduced. The values of the instantaneous speed with multiple runs of the line length drop to 250 m / μs. The average speed of a traveling wave with a single run of the line decreases by 4-6% relative to the speed of light for real thresholds of signal registration.
