Cable Fault System
Modular Cable Fault Pre-location and Pinpointing
Portable Cable Fault Location System
Go to Our Services >>Introduction
T32 consists of three parts:
Built for 0–500kV power cable networks, this system combines a voltage booster, rectifier, pulse capacitor and discharge controller into one compact, highly reliable unit. By delivering periodic high-voltage impulses, it triggers fault point breakdown to work alongside TDR reflectors and pin-pointers for exact fault measurement and localisation. Precision electronics and lightweight engineering ensure safe, rapid troubleshooting that drastically cuts power outage duration.
Key Applications
Use the surge generator to break down the faulty cable, observe the TDR waveform to get the predetermined fault position, then use the pin-pointer to accurately locate the fault.
Automatic determination of cable end and fault location in LV TDR and ARM.

When used alone, WL50+ can test cable length or pre-locate joint positions. Low-resistance ground faults can also be directly pre-located.
LP30/4+ can generate 32kV DC/surge voltage for breakdown of fault points. It can also be used independently or adapted to any pin-pointer.
Receives the acoustic-magnetic time-difference signal at the fault point and can be adapted to any surge generator.
