Flir Si2a-PD Partial Discharge Fixed Acoustic Imaging Camera (with Wi-Fi)

The FLIR Si2a-PD Partial Discharge Fixed Acoustic Imaging Camera (with Wi-Fi) provides continuous 24/7 monitoring of electrical assets, helping identify partial discharge (PD), corona, arcing and other electrical anomalies at an early stage. Designed for permanent condition monitoring, it gives maintenance teams continuous visibility of critical equipment, helping reduce the risk of unplanned outages, emergency maintenance and costly electrical failures.

With 124 low-noise MEMS microphones and a 2–130 kHz acoustic bandwidth, the Si2a-PD detects and locates acoustic activity across a wide range of electrical applications. It can operate from distances of 0.3 m up to 200 m, with directional resolution from 1° down to 0.125°. Real-time sound visualisation provides additional information when investigating detected acoustic events and assessing the condition of electrical assets.

Partial Discharge Detection

The camera can detect, locate, assess and classify different types of partial discharge activity. Its PD recognition capabilities include surface and internal discharge, positive and negative discharge, corona, negative corona and floating discharge. Automatic PRPD pattern recognition helps identify characteristic discharge patterns, while AI-based severity assessment evaluates detected activity and provides recommended actions to support maintenance decisions.

Continuous monitoring allows the Si2a-PD to identify developing faults that may not be present during a scheduled inspection. It is suitable for transmission, distribution and substation assets, as well as permanent monitoring of medium- and high-voltage switchgear in industrial facilities. The camera can also be used with gas-insulated switchgear (GIS) to help identify insulation degradation, moisture ingress and contamination before they develop into more serious problems.

Intelligent Monitoring Wireless Connectivity and Integration

AI-enhanced detection and analysis helps deliver consistent results with minimal operator input. FLIR AssetLink™ compatibility allows multi-sensor information to be associated with individual assets, providing a more complete overview of asset health. Enterprise-ready integration and data management capabilities make the Si2a-PD suitable for larger condition-monitoring systems and maintenance workflows.

Wireless connectivity provides additional flexibility when integrating the camera into a monitoring network. The Si2a-PD supports Wi-Fi at both 2.4 GHz and 5 GHz and is compatible with IEEE 802.11 b/g/n/ac standards. This allows the camera to connect wirelessly within suitable network environments without changing its core acoustic monitoring capabilities.

Visual Verification

A 12 MP colour digital camera provides a 75° diagonal field of view for additional visual context. Streaming video is available at 15 fps with a 960 × 540 resolution, while snapshots can be captured at 30 fps. Together with the acoustic information, the optical camera helps operators investigate and assess detected electrical anomalies.

Main Applications

Typical applications of the Si2a-PD include:

  • Continuous monitoring of transmission, distribution and substation assets
  • Early detection of electrical faults and partial discharge activity
  • Permanent monitoring of medium- and high-voltage switchgear
  • Condition monitoring in industrial electrical facilities
  • Partial discharge monitoring of gas-insulated switchgear (GIS)
  • Detection of insulation degradation, moisture ingress and contamination
  • Identification of corona, arcing and other electrical anomalies
  • Predictive maintenance and asset health monitoring
