FLIR Si2a-PD

FLIR Si2a-PD Fixed-Mount Acoustic Imaging Camera for Partial Discharge Detection Continuous 24/7 acoustic monitoring for partial discharge, corona and arcing in medium- and high-voltage environments. The Flir Si2a-PD keeps a constant listen on your most critical electrical asset, detecting, locating, and assessing partial discharge, corona, and arcing early, from up to 200 m (656 ft) away, so you can keep teams out of hazardous areas and prevent faults from turning into outages, incidents, or costly downtime. AI-enhanced detection and analysis turns complex signals into clear, actionable insight with minimal intervention, while its IP66-rated, VESA-mountable design makes permanent installation simple in harsh environments and easy to integrate into your wider data systems—so your switchgear, substations, and GIS stay safer, stronger, and continuously operational.

The FLIR Si2a-PD supports continuous monitoring across grid infrastructure, transformers, GIS, switchgear, substations and cable connection points, helping teams detect partial discharge activity before faults become failures. Grid Assets Transformers GIS Switchgear Substations Cable Joints WHY IT MATTERS Smarter monitoring. Safer decisions. Continuous acoustic monitoring helps maintenance teams detect risk earlier, work from a safer distance and respond with confidence before electrical faults escalate. Always-On Electrical Guardian Provides continuous 24/7 monitoring to detect partial discharge, corona, arcing and other electrical anomalies early. See the threat from up to 200 meters Detects, locates and assesses PD faults from up to 200 m / 656 ft, supporting safer diagnostics from a distance. AI turns noise into answers AI-enhanced analysis turns acoustic signals into clear, actionable insight with minimal operator input. KEY CAPABILITIES Engineered for continuous acoustic monitoring.
