Why Breakpoint Detection Matters？
When a cable’s internal medium is damaged, the fault is hidden beneath the insulation and cannot be seen visually. Maintenance teams often troubleshoot in sections, measuring voltage or continuity at multiple points to narrow down the fault location. Accurate detection minimizes unnecessary cable replacement and ensures system reliability.
Proven Methods to Detect Cable Breakpoints
-
Multimeter Detection Method Connect one end of the cable to a live wire, leave the other end unconnected, and use a multimeter to track voltage along the cable. Sudden drops in voltage indicate the breakpoint location. This method works well for shorter cables.
-
Inductive Pen Detection An induction test pen can detect voltage and continuity. By moving the pen along the cable, technicians can locate the breakpoint within a margin of 10cm. This method is effective for short to medium cable lengths.
-
Audio Detector Audio detectors send single or complex frequency signals through the cable to identify continuity faults. This non-invasive method avoids peeling insulation and quickly pinpoints breakpoints.
-
Cable Fault Tester Cable fault testers are comprehensive tools capable of detecting high-resistance faults, grounding issues, short circuits, and disconnections. Equipped with acoustic measuring pointers, they provide precise fault locations for power and communication cables.
-
Broken Line Detection Method By connecting a multimeter across a cable and bending sections, technicians can identify intermittent faults. This technique is suitable for short cables with frequent bending points.
-
Acupuncture Test (Not Recommended) Steel needles are inserted into the cable to measure continuity, but this damages insulation and is risky in high-humidity environments.
-
Pulling Wire Detection (Not Recommended) This method involves physically pulling the cable to locate faults near the ends. It is rarely used due to the risk of further insulation damage.
