FLIR Si124-PD™
Industrial Acoustic Imaging Camera
for Partial Discharge Detection
Example of Si124 PD severity assessment
The FLIR Si124-PD is an easy-to-use, stand-alone system for detecting
partial discharge problems in high-voltage electrical systems. This
lightweight, one-handed solution is designed to help engineering
professionals identify issues up to 10 times faster than with traditional
methods. With 124 microphones, the Si124-PD produces a precise
acoustic image that visually displays ultrasonic information, even in loud
environments and at long distances. The acoustic image is overlaid in
real time on a digital camera picture, which allows the user to accurately
pinpoint the source of the sound. Users can then apply the FLIR Severity
Assessment analysis to classify the severity of the issue and provide
guidance on recommended actions to resolve the problem. The Si124-PD
features a plugin that enables users to import acoustic images to FLIR
Thermal Studio suite for offline editing, analysis, and advanced acoustic
and thermography report creation. Field analysis and reporting can also
be done using the FLIR Acoustic Camera Viewer cloud service. Through
a regular maintenance routine, the FLIR Si124-PD can help facilities save
money on repairs and increase asset reliability. www.flir.com/Si124-PD
