A fixed-mount acoustic imaging camera built to watch energized electrical assets around the clock.
Teledyne FLIR will bring the new FLIR Si2a-PD to Electric & Power Indonesia 2026 — a fixed-mount acoustic imaging camera built to watch energized electrical assets around the clock. It joins the portable Si2-Series, iXX-Series, Exx-Series and T-Series cameras at Booth #2501 in Hall A, September 2–5 at the Jakarta International Expo.
Partial discharge is intermittent. A quarterly inspection catches it only if the discharge happens to be active when the inspector walks past. Closing that gap is what the Si2a-PD is for.
Si2a-PD: An Always-On Electrical Guardian
The Si2a-PD detects, locates, classifies and assesses partial discharge, corona and arcing from 0.3 m (1.0 ft) up to 200 m (656 ft). An array of 124 low-noise MEMS microphones covers a 2 kHz to 130 kHz bandwidth and overlays the acoustic image on a 12 MP color camera view with a 75° field of view.
AI-based severity assessment ranks what the camera finds and recommends an action, so the output is a maintenance decision rather than a waveform for someone to interpret. The unit is IP66-rated with VESA mounting for switchgear rooms, GIS and outdoor substations, and it feeds FLIR Assetlink™ for event tracking and integration into existing digital maintenance workflows.
“Partial discharge is often intermittent and can therefore be difficult to capture during routine inspections,” said Darrell Taylor, Business Director for Acoustics at Teledyne FLIR. “With the Si2a-PD, customers gain continuous visibility into their assets, enabling earlier detection, improved reliability, and more informed maintenance decisions.”
Si2-Series: The Portable Counterpart
Where the Si2a-PD stays mounted, the Si2-Series goes to the asset. The Si2-PD locates partial discharge in high-voltage equipment. The Si2-LD finds pressurized leaks and mechanical faults. The Si2-Pro does both and quantifies gas leaks, including hydrogen, CO₂, methane, helium, argon and ammonia. All three use the same 124-microphone array and the same 200 m reach in a one-handed camera that takes minimal training, and the Si2x models carry that capability into ATEX and HazLoc classified areas.
iXX-Series, Exx-Series and T-Series: Thermal on the Same Stand
Thermal imaging remains the fastest way to find a loose connection or an overloaded conductor before it fails. The iXX-Series — the i34 at 240 × 320 and the i64 at 480 × 640 — runs guided workflows on the camera itself and uploads results automatically to FLIR Assetlink™ for route planning or FLIR Ignite™ for trend tracking and work order generation through a connected CMMS.
The Exx-Series runs from the E54 up to the E96, which images at 640 × 480 and measures to 1500°C (2732°F), with laser-assisted autofocus on the E76, E86 and E96. The T-Series adds a 180° rotating lens platform for overhead and floor-level targets and an optional 6° telephoto lens for reading terminations from outside the fence line.
