Inspection Methods for Potential Arc Flash Incidents
Ultrasound inspection is an effective screening tool for detecting the potential for arc flash incidents. When hand-held ultrasonic instruments are used to scan enclosed electrical apparatus, the procedure is fast, accurate and simple. It can help inspectors by eliminating the need for wearing cumbersome PPE during a preliminary survey. On-line continuous monitors can alarm personnel of the presence of arcing, tracking and corona in advance of an inspection.
