Product Announcement from Aerovox Corp.
The reason the end device is called a cable thumper is due to the sound you hear when the discharged energy hits a fault. The ground actually "thumps", and this event is picked up by the end system. Aerovox capacitors are selected for use in these systems due to their durability and high energy density. Large single capacitors can be used in place of a conventional bank of lower power units.
