Electrical failures pose a tremendous safety threat and have the ability to shut down operations entirely.

Electrical discharge is a constant threat to your safety – and the health of your electrical systems. Ultrasound solutions reveal electrical fault conditions such as partial discharge (corona), partial arcing (tracking) and arcing discharge insidemetal clad switchgear, around substations, and in overhead transmission and distribution lines. Use SDT to hear what you cannot see.

Electrical faults such as arcing and tracking and corona discharge emit ultrasound signals at the site of the failure, often without generating any heat. Detect partial discharge at its infancy before it advances to an arcing or tracking condition. Safely inspect metal-clad switchgear prior to opening panels for infrared inspections.

Pair your SDT270 or SDT200 ultrasound solution with various ultrasound sensors to extend your range and capabilities for all electrical applications.
