Flir launched the Si2a PD, a fixed-mount acoustic imaging camera designed to deliver continuous, always-on monitoring of partial discharge (PD) in medium to high-voltage utility and industrial environments.
By capturing intermittent and transient events that traditional inspections often miss, the Si2a PD helps utilities detect faults earlier and take action before they lead to failures or outages.
Continuous Monitoring for Critical AssetsThe Si2a PD is designed to support proactive maintenance strategies by providing uninterrupted monitoring of electrical anomalies, including partial discharge, corona, and arcing, and ensuring that no critical event goes undetected, even during peak load conditions or outside scheduled inspections.
It combines acoustic imaging with AI-driven detection and classification, providing clear visualization and actionable insights into asset condition.
This enables maintenance teams to prioritize interventions, reduce manual inspection effort, and improve overall operational efficiency.
Flir launched the Si2a PD, a fixed-mount acoustic imaging camera designed to deliver continuous, always-on monitoring of partial discharge (PD) in medium to high-voltage utility and industrial environments. Building on the advanced performance of Flir’s handheld Si-Series acoustic cameras, the new Si2a PD introduces the company’s first-ever permanently installed acoustic solution that continuously monitors critical assets such as substations, switchgear, transformers, and gas-insulated systems (GIS). By capturing intermittent and transient events that traditional inspections often miss, the Si2a PD helps utilities detect faults earlier and take action before they lead to failures or outages.
Continuous Monitoring for Critical Assets
The Si2a PD is designed to support proactive maintenance strategies by providing uninterrupted monitoring of electrical anomalies, including partial discharge, corona, and arcing, and ensuring that no critical event goes undetected, even during peak load conditions or outside scheduled inspections. With the camera faults can be detected in distances up to 200 m. This offers a safer, non-contact monitoring in energized environments The device is built for harsh conditions, with IP66-rated protection for outdoor substations and industrial sites.
Advanced Detection and Actionable Insights
The Si2a PD is purpose-built for utility transmission and distribution networks, as well as energy-intensive industrial facilities where asset reliability is critical. It combines acoustic imaging with AI-driven detection and classification, providing clear visualization and actionable insights into asset condition. This enables maintenance teams to prioritize interventions, reduce manual inspection effort, and improve overall operational efficiency.
Integrated with the Flir AssetLink™ ecosystem, the system supports data recording, event tracking, and seamless integration into digital maintenance workflows, helping teams move from periodic inspections to continuous condition monitoring.
