Arc Discharge Generator
ADG-200-2 “STINGRAY”

Arc Discharge Generator ADG-200-2 is designed to work on finding cable faults in a complex with TDR RI-407 / TDR-107 / TDR-109 and with other manufacturers TDRs(supporting ARM and the ICM/Decay measurement methods) substantially enhances their the ability to determine the locations of high-resistance defects that cannot be localized by the low-voltage pulse(TDR) method.
