Applications

1.Accurate Partial Discharge Detection:Real-time captures partial discharge signals inside power equipment (e.g., transformers, switchgears, cables, instrument transformers), precisely locating the discharge position and intensity.
2.Early Warning for Insulation Hazards:Judges potential issues like insulation aging or damage through test data, issuing early warnings before serious failures (such as short circuits or breakdowns) occur.
3.Ensure System Safe Operation:Prevents power outages caused by insulation failure, reduces operation and maintenance costs as well as safety risks, and extends the service life of power equipment.
4.Multi-scenario Adaptation:Supports offline on-site testing, online real-time monitoring, factory quality inspection and other scenarios, meeting the needs of power engineering, industrial production, etc.

Key Configurations

High-sensitivity sensors: Equipped with ultrasonic sensors, UHF (Ultra-High Frequency) sensors, and TEV (Transient Earth Voltage) sensors for some models, capturing weak discharge signals without omission.

High-precision data acquisition module: Sampling rate up to 1GS/s, resolution ≥12 bits, ensuring accurate and distortion-free signal collection.
Anti-interference unit: Built-in digital filtering and noise suppression technology, effectively shielding electromagnetic interference on power sites.

Portable host: Lightweight (≤5kg) with large-capacity lithium battery (battery life ≥8 hours), suitable for on-site mobile testing.

Technical Specifications
