detecting Electrical Analysis

For more accurate diagnosis, ultrasound spectral analysis software helps identify sound patterns related to electrical emissions through spectral (FFT) and Time Series screens. Some of the more advanced instruments have on-board sound recording while others have on-board spectral analysis screens to help provide a diagnosis on the spot.

  • Ultrasonic Electrical Inspection: Corona, Are You

    When performing an ultrasonic electrical inspection, the ultrasound technician may select 40 kHz to detect an electrical anomaly (sound waves moving through the air). However, if background noise or other competing sounds are present, raising or lowering the frequency 1 kHz to 3 kHz may limit the interference, allowing the user to detect and define the electrical anomaly.
