CFL.2000ST High Voltage Cable Fault Location System

The CFL.2000ST is a highly integrated, fully automated digital software-based cable fault location system designed for advanced testing and diagnostics of high-voltage power cables. It supports a wide range of functions including surge generation, TDR-based fault pre-location, acoustic pinpointing, sheath fault location, VLF testing with Tan Delta, dielectric loss measurement, and insulation resistance testing.

With its modular design and intuitive Windows-based control interface, the CFL.2000ST combines multiple fault location and diagnostic tools into one compact, powerful platform.
