The FLIR Si2a-PD Fixed-Mount Acoustic Imaging Camera provides continuous monitoring of electrical assets to detect partial discharge (PD), corona, arcing, and other faults at an early stage. It can detect and assess PD activity from up to 200 m (656 ft) away, helping keep personnel clear of hazardous areas. Featuring AI-enhanced analysis, an IP66-rated housing, VESA mounting compatibility, and system integration capabilities, it is suitable for switchgear, substations, and GIS applications.
