Overview

Overview

With a split and rugged design, we made T32 to be one of the world's most portable and powerful cable fault locators. We built 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 onlyuse Pinpointer to locate a fault while you already have a surge generator.

T32 consists of three parts

  • Fault location surge generator, model LP30/4+
  • Cable fault pre-locator (TDR), model WL50+
  • Cable fault pin-pointer, model PP20
