IRISS – Principles of Airborne / Structure borne Ultrasound

May 13, 2019 – May 17, 2019 all-day

Ultrasonic detection equipment has become a trusted source for trending and troubleshooting over the last few decades. The ability now to run the sound waves through a sound analysis software has opened a new realm of things for the inspectors. No longer is Ultrasound simple a Go No Go test it can be used for determining Stray Voltage in a motor, Inner & Outer Race faults, Cage Faults, Ball Pass Faults, Corona, Track, Arcing, Loose connection, Delamination of Windings in a Transformer. These issues can be determined by simply looking at the images of the sound wave. Each one will have a distinct image that shows the Harmonic Marks that tell us the Fault Frequency of those Harmonics. In addition, the use of a Time Series will show the harmonics and the Amplitude of the Sinusoidal Wave. The Students will walk away with a much greater understanding of the Theory of Ultrasound and the use of their Ultrasound Inspection Equipment.
