A system for analyzing the behavior of ions in an insulation film is provided with a pulse voltage generator (402), a rolled element (403), an arithmetic device (405, 406), and a display device (407), and finds the ion density distribution within the insulation film by detecting, using the rolled element (403), ultrasonic waves generated within the insulation film by pulse voltage applied by the pulse voltage generator (402). The arithmetic device (405, 406) finds the ion density distributions within the insulation film at at least two different times from the detection result of the ultrasonic waves (105), and performs an advection-diffusion calculation on the basis of the ion density distributions at said at least two different times to find the ion density distribution within the insulation film at an arbitrarily defined time (107). The display device (407) displays the ion density distribution within the insulation film at the arbitrarily defined time (108). |
