The process of electrical inspection with ultrasound: search, detect, localize, report. SONOTEC SONASCREEN & SONAPHONE

The electrical inspection process

  1. Inspect the plant with our ultrasonic devices. 
     
  2. Detect sound emissions from a safe distance with the acoustic camera or parabolic sensor. Find failures reliably even in loud industrival environments.
     
  3. Pinpoint the exact location of partial discharges and document defects for later repair. 
     
  4. 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.
