Shaft Voltage Test Kit

November 10, 2011
The new AEGIS™ Shaft Voltage Test Kit makes it easier than ever to measure and document damaging VFD-induced voltages while there is still time to head off bearing damage and equipment downtime, according to the manufacturer. Because 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.
