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

The FLIR Si2-PD acoustic imaging camera helps you reduce maintenance costs for electrical equipment by offering an effective solution for partial discharge (PD) detection and response. This camera detects, locates, classifies, and assesses PD faults from up to 200 m (656 ft) away, identifying PD issues 30 times smaller than previously possible. It provides on-camera and software-based severity assessments, giving you the decision support needed for precise maintenance decisions.

For specific applications, you can choose the Si2-LD for leak detection and bearing fault detection, or the Si2-Pro for comprehensive electric utility, leak detection, and bearing fault detection applications. These models are available in the related products section, allowing you to customize your maintenance approach to suit your needs.

Key Features

  • Detect, locate, classify, assess partial discharge (PD) faults from up to 200m (656 ft.) away
  • Identify PD 30x smaller than ever before
  • On-camera, software-based severity assessment of PD issues/PD type classification provides best-in-class decision support
