FLIR T912305 Si2-PD Acoustic Imaging Camera for Partial Discharge Detection

The FLIR T912305 Si2‑PD, is a high-end industrial acoustic imaging system engineered for partial discharge detection, classification, and severity assessment. It uses a large MEMS microphone array to visualise ultrasonic emissions from partial discharge activity and overlays this information on a digital camera image, enabling fast, safe, long distance monitoring of electrical devices.

This devices primary functions are detect, locate, classify & assess partial discharge faults up to 200m (656ft), identify partial discharge events 30× smaller than previously possible, and provide on-camera AI‑based severity assessment with recommended actions.
