Description
Overview
GAOTek Underground High Voltage Cable Fault Locators with a split and rugged design, we made T32 to be one of the world’s most portable and powerful cable fault locators. We build in kinds of time-domain reflectometer (TDR) methods to pre-locate faults, like LV (low-voltage) TDR, Arc Reflection method (ARM), Impulse current decoupling method (ICE). For multiple types of cable faults. All parts can be used independently. You can only use our TDR part to test the length of a cable or can only use pin pointer to locate a fault while you already have a surge generator. By using the surge generator to breakdown, the faulty cable observes the TDR waveform to get the pre-determined fault position, and then uses the pin pointer to accurately locate the fault.
