AEGIS Test Kit Measures Motor Shaft Voltage
The new AEGIS Shaft Voltage Test Kit makes it easy to measure and document damaging variable frequency drive (VFD)-induced voltages while there is still time to head off bearing damage and equipment downtime.
The kit can test every VFD-controlled motor in a whole production plant, office building, mechanical room, or anywhere else VFD-driven motors are operating, it provides a powerful tool for maintenance personnel and testing contractors — anyone who needs to determine and convince others that a motor is or is not subject to stray shaft voltages great enough to harm motor bearings.
The result of a collaboration between Electro Static Technology (EST) and Fluke Corporation and available from both companies, the kit includes a special replaceable probe tip for highly accurate voltage readings on rotating equipment.
Designed by EST, this tip is the first of its kind, containing high-density conductive microfibers that ensure continuous contact with a rotating motor shaft. EST manufactures the tip and extension rod that may be held or used with an optional magnetic base, while Fluke makes the 10:1 probe itself and the Fluke 190 Series ScopeMeter portable oscilloscope that displays the voltage waveform and saves the image for reporting.
