Order an EZ-Thump configured to your specific needs. To determine the catalog number, fill in the alpha characters with the corresponding numbers from the detailed options. Example: to order a 4-kV EZ-Thump with 15 ft output and ground cables, 14 mm male MC with vise grip cable termination, hand cart and sheath, request catalog number EZT4 - 15 T2 C H.
The Megger EZ-Thump (originally manufactured as the Seba EZ-Thump) is the compact and light weight, battery or mains powered solution for the fault location in MV or LV cables. It presents the ideal supplement for a satellite-based concept in areas of lower distribution density and failure rate, where fast reaction, weight, size and economy are the driving factors. The system requires no adjustments and need only to be operated by a rotary encoder.
Due to their rugged yet portable enclosure, they are ideally suited either for use in 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.
On-board is a TDR with a 7.6 km range and arc reflection at 4 kV for pre-locating. For pinpointing, 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.
