Where HZ-FA-8 acoustic analysis engine is used
HZ-FA-8 is designed for online acoustic monitoring of power equipment and industrial assets. It captures audible and ultrasonic sound signatures through external sensors, analyzes voiceprint features at the edge, and supports characteristic alarms or AI-based abnormal sound recognition.
Transformer Acoustic Monitoring
Monitor transformer operating sound, cooler noise, load-related acoustic changes and discharge-related abnormal signals.
- Cooler abnormal sound recognition
- Heavy overload acoustic warning
- DC bias and discharge-related events
GIS Operation Sound Analysis
Analyze GIS operation sounds and acoustic differences between normal and abnormal switching states.
- Switching sound pattern monitoring
- Abnormal impact sound detection
- Time-frequency acoustic comparison
Distribution Box Sound Monitoring
Use compact external acoustic sensors to detect abnormal sound, impact, unstable operation and early fault signs.
- Abnormal sound pressure level
- Main frequency deviation
- Smoothness and stability changes
Cable Joint & Connector Monitoring
Detect acoustic or ultrasonic abnormalities around cable joints, connectors and power cable accessories.
- Surface discharge warning
- Corona discharge recognition
- Frequency band energy abnormality
Switchgear & Cabinet Monitoring
Support acoustic monitoring for switchgear cabinets, contact abnormality, mechanical operation noise and discharge-related events.
- Short-circuit impact alarm
- Loose clamp recognition
- Partial discharge acoustic features
Rotating Equipment Acoustic Monitoring
Monitor motors, fans, pumps and rotating equipment for unstable sound, bearing-related noise and abnormal acoustic patterns.
- Industrial abnormal sound monitoring
- Bearing and friction noise warning
- Edge acoustic feature analysis
