FLIR Si2-PD Acoustic Imaging for for Partial Discharge Detection

The FLIR Si2-PD industrial acoustic imaging camera helps you reduce maintenance costs for electrical equipment by offering an effective solution for partial discharge (PD) detection and response. This camera detects, locates, classifies, and assesses PD faults from up to 200 m (656 ft) away, identifying PD issues 30 times smaller than previously possible. It provides on-camera and software-based severity assessments, giving you the decision support needed for precise maintenance decisions.

For specific applications, you can choose the FLIR Si2-LD for leak detection and bearing fault detection, or the FLIR Si2-Pro for comprehensive electric utility, leak detection, and bearing fault detection applications. These models are available in the related products section, allowing you to customize your maintenance approach to suit your needs.

Dark coloured roofs captured by FLIR thermal camera

The Sizzling Impact of Dark Roofs and Urban Heat Islands

Dark roofs are popular in Australian urban areas but they come with a catch. Dark coloured materials absorb and retain a substantial amount of heat, increasing local temperatures, and fostering urban heat islands. Understanding the impacts of dark roofs on urban heat is crucial for developing sustainable solutions to mitigate their effects and building resilient cities. The
