The cable fault locator uses the principles of vibration pickup and electromagnetic induction to determine the specific location of cable fault points. A high-voltage pulse generator causes flashover discharge at the fault point, and the resulting vibration waves, sound waves, and electromagnetic waves are detected by the instrument's special probe for precise fault location.
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 high-voltage impulse to create discharge sounds at fault points, detected by sensitive acoustic sensors for accurate location.
3. Pure magnetic method: Detects pulse signals through induction coils to determine cable path and fault locations.
4. A-frame method: Uses potential difference measurements to locate ground faults in buried cables by detecting changes in electric field characteristics.
