The Cable Fault Pinpointer is professional portable equipment for precisely locating underground power cable fault points on the ground. Equipped with acoustic-magnetic synchronization, magnetic field detection and optional step voltage modes, it verifies positions crosswise for high accuracy. With intelligent algorithms, noise reduction, adjustable filtering and automatic gain functions, it simplifies field operation and supports cable path tracing synchronously, widely used in power cable maintenance projects.
Product Features
- Integrates multiple pinpointing methods: acoustic-magnetic synchronization method, step voltage method (optional function) and magnetic field intensity method.
- Mutual verification among various pinpointing modes guarantees accurate and reliable fault positioning results.
- Adopts intelligent positioning algorithm that directly calculates acoustic-magnetic delay values, lowering operation requirements for technicians.
- Equipped with automatic mute function to prevent noise generated during sensor movement from damaging users’ hearing.
- Displays left/right direction indication of the tested cable, enabling cable path tracing while pinpointing faults.
- Four adjustable levels of audio channel filtering parameters to suppress ambient noise by selecting proper filter settings.
- Built-in background noise reduction technology effectively filters environmental interference, highlights discharge sounds at fault points and improves the precision of acoustic-magnetic delay measurement.
- Automatic gain control realizes self-adjustment of magnetic field triggering gain for simpler fault pinpointing operation.
