The TDR screen shows a waveform. To the experienced eye, it's a story of the cable's entire life — every splice, every repair, every weakness. To the untrained eye, it's...

VLF vs DC Hipot: Choosing the Right Cable Commi...
Ask two cable engineers what the "right" field test for a newly laid 20 kV XLPE cable is, and you may get two different answers. One swears by VLF. The...

Velocity Factor: The Hidden 5% That Determines ...
Every cable fault locator engineer knows the embarrassment: the TDR says "the fault is at meter 780," you excavate at 780, and there's nothing there. The cable is fine at...

What Causes High-Resistance Faults in Cables?
The hardest cable faults to find aren't the dramatic short circuits — they're the quiet high-resistance faults that hide from test equipment and trip networks at the worst moments. Understanding...

High-Resistance Cable Faults: The Problem TDRs ...
High-resistance cable faults — insulation breakdowns above a few hundred ohms — are invisible to a standard TDR. The reflection is too weak to measure. Before you can pre-locate the...

Why Can't My TDR Find the Fault? 6 Real Reasons...
You've tested the cable twice. The TDR trace looks clean. But the network trips every night, and you know the fault is there. Frustrating? Absolutely. And more common than most...
