A **TDR cable fault locator** (Time Domain Reflectometer) sends fast-rising electrical pulses into power cables, analyzing reflected waveforms from faults like opens, shorts, or high resistance to locate them with ±0.2m accuracy over 100km. Pulse reflection principles measure round-trip time at near-light speed, enabling precise km-range detection for underground cables—ideal for utilities minimizing downtime with certified tools from Wrindu.

What Is a **Time Domain Reflectometer** and How Does It Work?
A **TDR cable fault locator** is a portable diagnostic tool that uses pulse reflection to detect cable imperfections by sending nanosecond pulses and capturing echoes. Impedance mismatches at faults cause partial reflections; time-of-flight calculation (distance = velocity × time/2) achieves sub-meter accuracy over several km for power cables with open circuits, shorts, and high-resistance faults.
How Do Pulse Reflection Principles Enable **Cable Fault Location TDR** Over Long Distances?
Pulses travel at ~200m/μs in cables; reflections from faults return proportionally to distance, allowing localization several km away without excavation. Waveform analysis—rising edges for opens, inverted for shorts—processed via high-speed sampling delivers ±0.2m resolution up to 100km. A 25m test line verifies setup for reliable **TDR for power cable faults** in field conditions.
