Megger EZ-Thump 12 kV, Model v3, Cable Fault Location System

The Megger EZ-Thump 12kV, Model v3 is a portable cable fault location system designed to make fault finding on underground medium voltage power cables faster, simpler and more practical in the field. Built as an all-in-one solution, it is well suited to utilities, contractors and first-response teams who need a compact unit that be transported easily and deployed without a complicated setup. Megger also positions it as easy to use for less experienced operators, while still offering the capability needed for demanding fault location work.

For pre-locations work, the EZ-Thump 12 kV combines and integrated TDR for low resistance faults with Arc Reflection Method functionality for high resistance faults, helping users identify fault distance before moving on to final pinpointing. It also delivers a 500 J surge at 12 kV for acoustic fault pinpointing when used with a compatible receiver, and supports sheath testing and sheath fault location as part of a broader cable fault workflow.

A major strength of the EZ-Thump 12 kV is its portability and straightforward operation. Operation is handled via a single rotary control with results shown on a bright colour display, while automatic mode helps speed up routine testing and expert mode gives more control for challenging applications.
