Teledyne FLIR Si2a-PD Acoustic Imaging Camera with Wi-Fi, PD, 130kHz, 656ft Range, Si2a Series

FLIR Si2a-PD Industrial Fixed Acoustic Imaging Camera for Partial Discharge Protection

Flir’s top of the line acoustic imaging series now comes in a fixed-mount option to give utility teams 24/7 monitoring of substations, switchgears, and transformers. The always-on Si2a-PD catches intermittent faults and peak load activity that spot checks often miss, recording events on-board and in the Flir Assetlink ecosystem.

Key Features

• Provides continuous 24/7 condition monitoring, enabling early detection of partial discharge (PD), corona, arcing, and other electrical anomalies to help prevent unplanned outages and improve operational safety
• Fixed mount acoustic imaging for continuous partial discharge detection plus corona and arcing.
• AI enhanced detection, classification, and assessment for confident decisions with minimal operator input and enables enterprise-ready system integration and data management
IP66 rated for outdoor substations and demanding industrial sites.
• Detect, locate, classify, and assess PD faults from up to 200 m (656 ft) away, supporting safe inspections, and integrates into Assetlink where multi-sensor data can be tagged to assets to provide a holistic summary about asset health

The Flir Si2a-PD keeps a constant listen on your most critical electrical assets—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.

Main Applications

• Early fault detection across transmission, distribution, and substation assets in electrical utility environments to reduce outages, emergency maintenance, and high-cost failures
• Continuous and permanent monitoring of medium and high voltage switchgear industrial facilities to identify early-stage partial discharge and prevent unplanned outages, safety risks, and costly downtime
• Condition monitoring of gas-insulated switchgear (GIS) to detect insulation degradation, moisture ingress, or contamination early and avoid catastrophic failures and expensive repairs
