Since electrical discharge development is very fast and influenced by the probability largely, strict condition control and high-resolution measurements are difficult. This paper describes numerical estimation of the sparkover voltages and time lag (V-t) characteristics utilizing a hydrodynamic numerical numerical modeling of a streamer and the equal-area criterion. V-t characteristics for a step voltage, a steep-front square voltage with a rise time of 20 ns, and 1.8/450 μs impulse voltage are successfully estimated using a single equal-area parameter obtained from the numerical modeling of the streamer. This suggests that a numerical estimation of V-t characteristics for any kinds of voltage wave form may be possible.
