The cable fault locator uses vibration pickup and electromagnetic induction principles to precisely locate cable faults. A high-voltage pulse generator creates flash over discharge at the fault point, with resulting vibration waves, sound waves, and electromagnetic waves detected by the instrument's special probe.
This instrument is suitable for locating various faults in power cables, high-frequency coaxial cables, street light cables, and buried wires, including low-resistance, short-circuit, open-circuit, high-resistance leakage, and high-resistance flash over faults.

1. Acousto-magnetic synchronization method: Combines traditional acoustic measurement with electromagnetic signal detection for precise fault location by measuring time differences between signals.
2. Pure sound method: Uses acoustic vibration sensors to convert sound signals into electrical signals for fault point identification through headphones or display.
3. Pure magnetic method: Determines cable path and fault location through pulse signal characteristics detected by induction coils.
4. A-frame method: Utilizes potential difference measurements to locate ground faults in buried cables through electric field analysis.
