Elec Machinery Systems Test Facility
Motor Test Lab. Based on work for NRC on life extension and aging of motor operated valves, studying reliability and harmonics of high efficiency motors. For large motors (50-100 hp and higher) harmonics measured back at transmission substation (with Commonwealth Edison).
Diagnostics (Steve McNeany). Remote temperature measurement and Electrical Current Signature Analysis--can see mechanical vibration, etc. by analyzing the current waveform, with exciting implications for assessing motor/systems condition on line.
