XC-2100E Time Domain & Fault Location Unit (TWFL / TDR)

XC-2100E
Download Product Specs

The XC-2100E is a Time Domain Fault Location (TWFL / TDR) analyzer designed for pinpointing faults in underground power cables.
Using high-resolution Time Domain Reflectometry (TDR) and Traveling Wave (TWFL) techniques, it identifies the exact distance to cable faults with high precision.
Its rugged build, fast sampling rate, and advanced waveform analysis make it ideal for utilities and cable maintenance crews.

Key Features
