The Megger EZ-Thump 12 kV V3 is a compact, portable cable fault location system for medium voltage distribution cables, delivering 300 J at 0-12 kV with a 0-12 kV DC proof test and insulation resistance measurement. It features TDR (52 km range) for low resistance faults, Arc Reflection Method (ARM) for high resistance faults, and surge/thumping for pinpointing, with automatic cable end and fault detection, plus optional sectionalizing in select markets.
The rugged, IP54-rated unit (450 x 350 x 250 mm, 32 kg) includes a 7-inch HiBrite color display and operates on a field-replaceable battery (4 hours) or AC power. The E-Tray interface automates testing, while a single jog knob, F-Ohm safety check, and user guidance simplify operation.
Data is transferable via USB. The kit includes the EZ-Thump unit, 10 m HV leads, mains cable, and carry case, with optional accessories like digiPHONE 2 for acoustic pinpointing or ESG-NT2 for voltage gradient. No warranty is specified, making it ideal for efficient fault diagnostics in utility and industrial settings.
