WL20 Cable Fault Pre-locator (TDR)

The WL20 is a portable, stand-alone, time domain reflectometer (TDR) designed for length testing and fault location on power cables encompassing all voltage levels, such as low voltage (LV), medium voltage (MV), and high voltage (HV) applications. Its primary focus is on long HVAC and HVDC installations, whether they utilise paper insulation or solid dielectric insulation.
With its straightforward graphic user interface, featuring a single rotary knob and the well-known piechart navigation, the WL20 ensures operator comfort and enables efficient operation. The device incorporates a large, bright color touchscreen that enhances ease of use and facilitates quick and accurate readings.
