Detect Electrical Discharge Defects with Ultrasound

Electrical discharge is more common than we’d like to believe; even in new installations. Detecting these defects poses a serious challenge, particularly at an early stage when there is still time to initiate corrective actions. Vigilant technologies help reduce the risk of arc flash explosion while enhancing the overall reliability of electrical assets.
While there is no one perfect inspection technique or technology which can, on its own, detect and localize every defect, ultrasound performs...
