Weighing less than 33 kg the EZ-Thump series are the most portable fault location systems on the market. It utilises the “Easy Go” test system, which is easy to operate, interprets the results and requires minimal training to find faults.

On-board is a TDR with a 7.6 km range and arc reflection at 4 or 12 kV respectively for pre-locating. For pinpointing, the EZ-Thump offers a surge energy of 500 J, d.c. testing for breakdown detection and insulation resistance measurement. The units are operated from line or the internal battery. They can fit in the boot of a car, making them ideal for a flexible quick response fault finding strategy.

All EZ-Thump models are compact, battery and AC line operated, portable cable fault location systems. They are designed for quick, effective, accurate and safe fault locating operations to greatly reduce system customer outage minutes.

Due to their rugged yet portable enclosure, they are ideally suited for all typical fault locating operations on MV cable as well as on LV cables.

The 12 kV model can be used as part of a “satellite” fault locating concept for remote areas that may have less frequent faults, when ease of operation, light weight and economics are important, or for hard to access inner-city locations.

The 3 kV and 4 kV units offer a convenient solution for industrial fault locating applications up to 3 or 4 kV, street light fault locating or fault locating in LV power circuits in the utility industry, featuring point-to-point cables.
