EMI Testing on rotating machinery helps diagnose electrical and mechanical problems in their early stages.

Capabilities

EMI Testing on Rotating Machinery Testing can identify problems in these and many other areas:

• Generator and motor stator windings
• Generator and motor bearings
• Motor power leads
• Generator isolated phase bus work
• Arcing generator shaft grounding brush
• Loose connections
• Open exciter diode fuses

Electrical insulation that is under duress exhibits partial discharges, creating electro-magnetic interference (EMI), a broadband electrical noise signal that can be monitored and trended. Our non-intrusive, predictive maintenance approach monitors both the targeted machine and anything connecting to it.
