LQ608 Digital Partial Discharge Tester: Advanced Field Diagnostics for Live Assets

The LQ608 is an ultra-portable partial discharge (PD) detection system engineered for field teams performing live inspections, fault localization, and condition assessment on high-voltage equipment. With military-grade ruggedness and advanced signal processing, it delivers lab-grade diagnostics in substations, tunnels, and remote sites.

Key Features & Capabilities

✅ Unmatched Portability
• Compact 8kg design (50% lighter than conventional PD systems)
• Vibration/shock-resistant casing (MIL-STD-810G compliant)
• 8-hour battery operation + vehicle charging

✅ Intelligent Signal Processing
• AI-based noise suppression (30dB+ interference rejection)
• Real-time TF-Map® (Time-Frequency mapping) for discharge separation
• Phase-resolved partial discharge (PRPD) & pulse sequence analysis (PSA)

✅ Live Equipment Testing
• Non-invasive HFCT/UHF/TEV sensors (sold separately)
• Dual-channel synchronization for cable fault localization
• On-screen voltage monitoring (PT/CT inputs)

✅ Rapid Reporting
• Automated PD intensity & trend logging
• GPS-tagged measurement records
• Wi-Fi/4G cloud data sync

Critical Applications

Technical Specifications

Why Field Teams Choose LQ608

Case Example: Locating GIS particle discharge in <15 minutes:

1. UHF sensors detect PD pulses at 876MHz

2. TF-Map® separates discharge from radio noise

3. Time-difference localization pinpoints defect within 0.5m

4. Automatic report generation with IEC 61869-3 severity classification

Operational Advantages:
• 60% faster setup vs. traditional PD systems
• No IT support needed – intuitive 3-step workflow
• Future-proof – firmware upgrades add new analysis modes
