High Voltage

Acoustic imaging cameras, otherwise known as sonic or ultrasonic imagers, are popular amongst facilities managers, especially those working in industrial or high-voltage settings. They are extremely easy to use and highly effective at finding air/pressurised leaks and partial discharge/corona. Acoustic cameras detect audible and/or ultrasonic sound; convert it into a sound map; then superimpose this map onto a digital image of the inspection area, allowing you to pinpoint the source of the leak or electrical fault accurately, simply, and quickly. As sonic imaging is a relatively new preventative maintenance/inspection technology, it can be difficult to know what makes a good acoustic camera. Thankfully, Teledyne FLIR has outlined six things to look for when purchasing an ultrasonic imager. Continue reading →
