TYPICAL ELECTRICAL components that can be inspected with ultrasound and infrared include:
• Load interrupter switches
• Motor control centers
• Terminal transition cabinets.
As a further complement to infrared inspections and to aid in the proper diagnosis of the condition, recorded ultrasounds can be seen in both FFT and Time Wave Form from spectrum analysis software – this will show how to properly diagnose electrical anomalies. This form of analysis is referred to as ultrasound imaging.
Ultrasound technology and electrical inspections
Ultrasound is probably the most versatile of any PdM technology. Typical applications for ultrasound include compressed air & gas leak detection, bearings, motors, gearboxes, valves, steam traps, hydraulic applications, and for condition-based lubrication of bearings and rotating equipment.
