Abstract
The invention relates to a method and to a device for improving the dische regime of an electric arc produced between two electrodes. The device is characterized in that it includes means an insulating element (32), preferably spherical in shape, for increasing the resistance to the passage of the electric arc (A) between ends of the electrodes (12, 14). By using the invention it is possible to obtain an arc discharge of the critically damped type. The method and the device are preferably used in shock wave generator apparatus for hydraulic lithotripsy.
