The AEGIS shaft voltage test kit measures and documents the voltages of motors controlled by variable frequency drives (VFDs). The kit can test every VFD-controlled motor at a facility to determine whether it is subject to stray shaft voltages great enough to damage bearings. The kit includes a replaceable probe tip with high-density conductive microfibers that ensure continuous contact with a rotating motor shaft. Electro Static Technology manufactures the tip and extension rod with optional magnetic base, while Fluke makes the 10:1 probe and the Fluke 190 Series II ScopeMeter portable oscilloscope that displays and saves the voltage waveform.
