Ultrasound inspection device for power equipment.


UIT-V1, the drive by primary distribution overhead inspection system, Is the most advanced version of ultrasonic detection methods for power facility.

UIT-V1 is the patented inspection system that uses the ultrasonic technology that allows user to detect degraded equipment in a moving vehicle that can travel as fast as 30km per hour. UIT-V1 captures ultrasound that is being emitted by faulty equipment with a pinpoint accuracy by using the state of art technology as far away as 30 meters or about 100 feet from the object.

The system enables distribution engineers to detect and replace faulty equipment before they fail, which offers utilities to proactively prevent any potential costly outages. The analytical diagnostic software provides engineers the level of degradation of faulty Equipment that allows engineers to plan distribution asset managements with ease.

Since the product and service offerting in 2008, UIT-V1 and its predecessor Inspector101, INDS-U2 have been implemented and used by utilities in korea and overseas.
