Ultrasonic Camera[BATCAM 2.0] Arc, corona discharge, floating discharge, surface discharge.

This video was taken with SMI BATCAM 2.0 to detect electric arcs, corona discharge, floating discharge, and surface discharge.
·BATCAM 2.0 is the world’s lightest and smallest ultrasonic/sound camera. It can be used for various objectives because it can measure not only signal in the audible range but also in the ultrasonic range. It has 112 microphones for high measurement sensitivity and can detect ultrasonic signals at 48kHz. BATCAM can clearly measure not only car BSR (Buzz, Squeak, Rattle), but also the minute air · gas leak, and the electric arc.
