Review demonstrates return-stroke velocity depends on energy supply rates for channel conductivity in transmission lines, highlighting key parameters for lightning protection.
The mechanism of lightning-stroke formation is reviewed, with emphasis on those aspects of particular interest to the transmission-line engineer. The relation between the return-stroke current and the velocity of its head is shown to be a function of the speed with which energy can be fed into the return-stroke channel to achieve the necessary conductivity
