Product Description

Product Overview

The Sansion Power TDR Cable Fault Locator is designed to help technicians identify cable discontinuities and estimate the distance to a suspected fault using time-domain reflectometry.

TDR technology sends an electrical pulse into a cable and analyzes the reflected signal caused by changes in impedance. By interpreting the waveform and applying the correct propagation velocity, users can estimate the distance to an open circuit, short circuit, joint, or other impedance discontinuity.

This method is widely used for cable troubleshooting, maintenance, installation checks, and preliminary fault investigation.

Key Testing Functions

TDR waveform measurement and display.
Fault distance estimation based on signal reflection.
Cable length measurement where supported.
Detection of applicable open-circuit and short-circuit faults.
Identification of impedance discontinuities and abnormal cable sections.
Adjustable propagation velocity and pulse settings, depending on the model.
Waveform storage and comparison where available.
Portable operation for field testing.

Applications

Power cable troubleshooting.
Control cable and industrial wiring inspection.
Communication cable testing, where compatible.
Cable maintenance and repair.
Electrical installation acceptance.
Preliminary diagnosis before excavation or cable replacement.

Common Customer Problems

Problem 1: The fault location is unknown.

TDR helps estimate the distance from the test point to a suspected cable discontinuity, reducing the area that needs further investigation.

Problem 2: Waveforms are difficult to interpret.

The displayed waveform provides useful diagnostic information, but correct interpretation depends on cable characteristics, instrument settings, and operator experience. Training and a clear user manual can help users obtain more consistent results.

Problem 3: The cable length or propagation velocity is uncertain.

Accurate distance estimation depends on the propagation velocity setting. Users should select an appropriate value for the cable under test and verify it against known cable lengths when possible.

Frequently Asked Questions

Q1: What does TDR stand for?

TDR stands for Time Domain Reflectometry, a method that analyzes reflected electrical pulses to identify impedance changes along a cable.

Q2: Can a TDR locate high-resistance faults?

Its ability depends on the fault characteristics. Some high-resistance or intermittent faults may not produce a clear low-voltage reflection and may require an alternative method or a complete cable fault location system.

Q3: What is the maximum testing distance?

The maximum range depends on the specific model, cable attenuation, cable construction, and test conditions. Please consult the applicable datasheet.

Q4: Is TDR suitable for energized cables?

Follow the instrument's operating manual and voltage limits. Unless the equipment is explicitly rated for the application, isolate the cable and verify that it is safe to test before connection.

Q5: What information should I provide when requesting a quotation?

Please provide the cable type, expected length, required measurement range, intended application, and any special functions you need.
