A digital simulation technology for over-voltage induced by lightning strikes on extra and ultra high voltage towers is presented, including the mechanism of the induced over-voltage and the design principle and process of the simulation program. Example shows that the new technology is better than the old one. The simulation result of the program was compared with the calculation result which uses the empirical equation and the measured data from artificial triggering lightning experiments, proving the simulation program correct and practical.
