Flir announces the launch of the Flir Si2a PD<\/a><\/strong>, 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.<\/p>\n\n\n\n

Building on the advanced performance of Flir\u2019s handheld Si-Series acoustic cameras, the new Si2a PD introduces the company\u2019s 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.

\u201cPartial discharge is often intermittent and can therefore be difficult to capture during routine inspections,\u201d said Darrell Taylor, Business Director for Acoustics. \u201cWith the Si2a PD, customers gain continuous visibility into their assets, enabling earlier detection, improved reliability, and more informed maintenance decisions.\u201d<\/p>\n\n\n\n

Continuous monitoring for critical assets<\/strong><\/p>\n\n\n\n

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.<\/p>\n\n\n\n

Key Benefits<\/strong><\/p>\n\n\n\n

\u2022 Prevent outages and improve reliability with early detection of PD, corona, and arcing
\u2022 Continuous 24\/7 monitoring to capture intermittent faults missed by periodic inspections\u2022 Detect, locate, classify, and assess faults from up to 200 m (656 ft)
\u2022 AI-enhanced analysis for accurate results with minimal operator intervention\u2022 Safer, non-contact monitoring in energized environments
\u2022 Built for harsh conditions, with IP66-rated protection for outdoor substations and industrial sites<\/p>\n\n\n

Advanced detection and actionable insights<\/strong><\/p>\n\n\n\n

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 prioritise interventions, reduce manual inspection effort, and improve overall operational efficiency.<\/p>\n\n\n\n

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.<\/p>\n","protected":false},"excerpt":{"rendered":"
