Flir Si2a PD is 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. 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. 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.
