Field testing the HIKMICRO AI56 Acoustic Imager on several objects including a small electric motor, a switchyard, and an in-depth analysis of a 13.8 kV generator stator during final and PD testing. For additional reading we recommend “Practical Partial Discharge Measurement on Electrical Equipment,” Wiley-IEEE Press, Stone, Cavallini, Behrmann, Serafino, published 2023. Acoustic Imaging PD information starts on page 96. We discuss our first experiences as we work our way through the operation of the instrument which does not include a manual or how-to video. The instrument was purchased from Monroe Infrared at monroeinfrared.com.
