Electro Static Technology: Motor Shaft Voltage Test Kit
December 31, 2011
Whether they drive HVAC fans or pumps, motors controlled by variable frequency drives (VFDs) are vulnerable to electrical bearing damage. The new AEGIS™ Shaft Voltage Test Kit is designed to make it easier to measure and document VFD-induced voltages while there is still time to head off damage and downtime, the company says. The kit includes a specially tipped probe and a portable oscilloscope.
