Whether they drive the fans and pumps of commercial HVAC systems or the conveyors of industrial production lines, motors controlled by variable frequency drives (VFDs) are vulnerable to electrical bearing damage. For retrofits, the new AEGIS™ Shaft Voltage Test Kit makes it easy to measure and document VFD-induced voltages while there is still time to head off damage and downtime. The kit includes a specially tipped probe and a portable oscilloscope.
