HV Cable Fault Pinpointer with Synchronous Acoustic-Magnetic Pinpointing, 5-inch Touch LCD, 0.1m Accuracy, 8h Battery

The XHDD503B HV Cable Fault Pinpointer is engineered for high-voltage cable fault location in demanding field environments. It employs synchronous acoustic-magnetic pinpointing and identification technology to precisely locate underground cable faults. The instrument completes precise fault positioning within rough measurement ranges, collects acoustic-magnetic signal time differences (up to 80ms), and integrates positioning technology with path-assisted testing. Multiple test modes with comprehensive diagnostic prompts ensure efficient, accurate fault location for professional HV field operations.

The instrument uses synchronous acoustic-magnetic positioning: an impact discharge generator creates flashover at the cable fault point, and the dedicated dual-channel probe simultaneously captures both acoustic and electromagnetic signals. Because the magnetic signal propagates near-instantaneously while sound travels considerably slower, the time difference between the two signals directly correlates to the distance from the fault point. The instrument's waveform display shows both signals in real time, with automatic time difference calculation (0-80ms range). By moving the sensor along the cable path and finding the point with the minimum time difference, the exact fault location is identified at 0.1m precision — far more reliable than traditional acoustic-only methods that rely solely on operator hearing.
