Megger EZ-Thump 12 kV thumper and TDR power cable fault locator

Click2Contact

The Megger EZ-Thump is a compact and lightweight portable cable fault location system that is also suitable for cable testing. It is designed for quick and safe fault-locating operations to reduce customer outage time. It is available to rent from TechRentals.

The unit incorporates a 12 kV hipot tester, time-domain reflectometer (TDR) and surge generator. It can be powered from an AC supply or internal batteries (3 h recharge time provides 30 m of thumping). The surge generator produces a 500 J, 0–12 kV @ 12 mA pulse. The kit includes the Digiphone Plus pin pointer with surge wave receiver to locate faults while thumping.

The device is suitable for both a ‘satellite’ fault-locating concept, designed for remote areas with less frequent faults, and for hard-to-access inner-city locations.
