The KDZD3099C Ultrasonic Partial Discharge Inspection Instrument is a detection device that diagnoses power line fault hazards by collecting and analyzing abnormal ultrasonic signals from power lines. It operates under live conditions (without power interruption) to determine the location and type of faults. The device captures ultrasonic anomalies via a sensor, which are then transmitted to the host. The built-in software analyzes the signals, converting them into audible sound signals and waveforms for output. This visualization and audio feedback help inspection personnel accurately identify line faults, thereby improving power supply reliability, work efficiency, and reducing labor intensity.

• Portable & Lightweight: Compact design, easy to carry, and operable by a single person.
• Non-Contact & Visual: Handheld, non-contact detection with visual waveform display and audible output.
