- Fault pinpointing (thumping)
- Optional Sectionalising software*
Weighing as little as 32 kg, the EZ-Thump 3 kV is the first of its kind in the market and, with updated EZ-Thump 4 kV, this series has the most portable fault location systems specifically for shielded and unshielded low voltage power cables.
These instruments use 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 3 or 4 kV respectively for pre-locating. For pinpointing, the EZ-Thump offers a surge energy of 500 J, at 1.5 and 3 kV or 4 kV respectively, DC testing for breakdown detection, and insulation resistance measurement.
This EZ-Thump series is also able to perform sheath fault testing and sheath fault location.
The units can be operated from the mains or using their internal battery. They can fit in the boot of a car, making them ideal for a flexible rapid response fault finding strategy.

FAQ / Frequently Asked Questions
Old paper-lead cables pose a big challenge when fault locating due to their different physical construction compared to modern solid dielectric cables. Instead of having to deal with carbon and air like in faulted XLPE- or EPR-insulated cables, PILC cables are made of lapped paper impregnated with mass or oil.Breaking down a fluid insulation medium, igniting and stabilising an arc in a fluid, and capturing useful fault traces with the radar is all far more difficult on paper cables than on solid dielectric cables. In particular, breakdown voltages of high resistance faults may be very high, and low resistance faults do occur significantly more often.To be truly effective on paper-lead cables, the fault location system used must have a high DC hipot, sufficient energy for cap discharge, and a modern TDR. With its 40 kV DC hipot, 2000 Joules at 32 kV and a radar with Multishot and de-attenuation features, the STX40 is well-equipped to be successful in finding faults even on PILC cables.
Occupational safety and safe working conditions are paramount for us and our customers. Therefore, Megger products are designed to be the safest in the market. The STX40 is no exception.The unit meets the strict requirements of VDE 0104. Equipped with a ground loop monitoring circuit (F-Ohm) and a touch potential monitoring circuit (F-U or F-Voltage), STX40 is a milestone and is the portable fault location system with the highest safety standards in the market by far.
