XHDD503E Cable Fault Pinpointer with Acoustic-Magnetic Sync for Underground Cables

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.

• 5-inch touch-high brightness LCD ensures visibility under sunlight
• 4 test modes: standard, enhanced, noise reduction, and customized
• 4 positioning functions: acoustic-magnetic synchronization, pure acoustic, pure magnetic, and step voltage
• Background noise reduction technology with multiple filtering options
• Equipped with BNR and mute functions
• Path deviation indication capability
• Multi-layer physical isolation signal sensors with IP65 waterproof rating
• Built-in large-capacity lithium battery with long standby time and fast charger
• Compact, lightweight design with simple human-machine interface

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.

• Cable fault locator main unit
• Probe with connecting rod
• Headphones for signal feedback
• 7-core signal cable
• Charger
• A-frame for step voltage testing
• A-frame connection cable
• Ground pin accessory

The A-frame automatically enters test mode when connected. The red and green indicators show signal strength changes as you approach the fault point, with maximum deflection occurring approximately 5 meters before and after the fault location.
