Brand: Megger

Model: ST16

The Megger ST16 Portable Cable Fault Location System represents a new generation of advanced underground cable fault locating systems that require less training than a traditional thumper-only system. It is the only fault locator with built-in intelligence to interpret the results of the initial test sequence.


The “turn & click” rotary button operation lets the user automatically proof test, pre-locate, and pinpoint the fault from one convenient control console. No adjustments are required. The unit automatically sets the thump voltage to minimize the stress applied to the cable. The ST16 features an automatic safety check to protect the user from incorrect or fault ground connections (F-Ohm).


This fully inegrated system can be operated from either its internal battery/inverter, external 12 VDC or 120/230 VAC.
