Surge Arc Discharge Generator ADG-500 “STINGRAY”

ADG-500

Arc Discharge Generator ADG‑500 is a 10kV/500J Surge generator with built-in ARM (aka SIM/MIM) and ICM (aka WAVE) fault location modes.

Surge generator and cable fault Pre-location in one compact and light weight device.
Significantly expands your ability of cable fault location of high-resistance defects which are not localize with low-voltage TDR method.

Overview

Supported measurement methods

Device provides the necessary conditions for the application of these modern non-destructive (without burning the insulation) search techniques of high resistance faults on power cables:
