Description

R-TDR is a powerful and compact reflectometer specially designed to locate low-voltage cable faults. Its multiple configurations and functions ensure high-accuracy measurements, even at short distance (< 5 m) and on live low voltage cables (max 400 VAC). A clearly designed LCD display constantly indicates all settings, avoiding confusing information.

The REFLEX R-TDR ICE reflectometer uses the Time Domain Reflection Method, sending low voltage electric pulses along the conductor with pulse width of nano to microseconds. Each change in impedance produces partial reflection of the pulse back to the equipment. The reflectometer calculates the distance using the time between the transmitted pulse and reflection, and the information obtained is later displayed graphically on the screen. In this way, cable ends, short circuits, interrupts, joints and cross-talks can be identified.

In ICE mode (Impulse Current Method) it allows the pre-location of high resistance faults and intermittent flash faults. Through the use of a current pulse generator of the GIC family, a discharge is triggered on the fault present in the conductor and results in a phenomenon of multiple reflections that are repeated as long as the voltage is sufficient to continue priming the fault. These reflections are captured by the inductive coupler and displayed on the screen, the time elapsed between reflections is proportional to the distance between the generator and the fault.
