ULD-40 ULTRASONIC CORONA ARCING DETECTOR

ULD-40 Ultrasonic Corona Arcing Detector
The ULD-40 is an Ultrasonic Corona Arcing Detector designed for corona and arcing inspections for predictive maintenance in electric utilities. Corona effect occurs when electricity is discharges into the surrounding atmosphere form a high voltage source.  Corona effects and electrical arcs in the air emit ultrasounds. The role of the ULD-40 consists of capturing emitted ultrasounds and of translating them into the audible range. This equipment is perfect for high voltage maintenance program.

Advantages of the ULD-40

The ULD-40 enables to make remote acoustic inspections with great accuracy.
The equipment is user friendly and does not necessitate any training whatsoever.
One of the advantages of the ULD-40 is that it just works as well in noisy environments.
The applications of the ULD-40 are countless and make it a global leak detection tool: a must for any prevention/maintenance department.
