Partial discharge detection with SONAPHONE
Detect damages at their earliest stages with our modular ultrasonic testing device and specialized broadband sensors.
- Broadband parabolic sensor BS30 for inspections over distance
- Record ultrasound data, sound levels, spectra, and converted audio
- Go-to tool for maintenance – multiple applications in one device
Reduce repair costs and increase plant reliability.
Easily detect partial discharges at early stages and improve your maintenance program!
The electrical inspection process
- Inspect the plant with our ultrasonic devices.
- Detect sound emissions from a safe distance with the acoustic camera or parabolic sensor. Find failures reliably even in loud industrival environments.
- Pinpoint the exact location of partial discharges and document defects for later repair.
- Report your findings for further analysis and evaluation by generating a PDF report. When using SONAPHONE Pocket, manually write a report. Repairs can then be arranged.
