Cable Fault System
Modular Cable Fault Pre-location and Pinpointing
Portable Cable Fault Location System
Go to Our Services >>Introduction
T20 consists of three parts:
Featuring a rugged, modular design, the T20 is a compact yet powerful cable fault locator equipped with TDR, Arc Reflection (ARM, optional), and Impulse Current (ICE) methods to solve cable faults. Each component functions independently, letting you use the TDR solely for length measurements or pair the pinpointing system with an existing surge generator.
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. ARM is optional.
When used alone, WL20 can test cable length or pre-locate joint positions. Low-resistance ground faults can also be directly pre-located.
LP30/2 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.
