    New AEGIS® iPRO-MR Monitoring Ring Combines Shaft Grounding and Shaft Current Monitoring for Critical Applications

    Electro Static Technology’s new AEGIS® PROMR Ring combines shaft voltage bearing protection with continuous monitoring of shaft voltage levels from a remote location—all in real time. The AEGIS® PROMR is an AEGIS® Shaft Grounding Ring and a shaft monitoring ring in one, ensuring optimum uptime and reliability of large motors and generators in critical applications. The PROMR is ideal for the protection of motors in remote locations that cannot be easily monitored or maintained.

    Rugged, highly reliable, and maintenance-free split rings, AEGIS® PRO Series Rings prevent damage that could cause generator or motor failure, unplanned downtime, costly repairs, and lost revenues.  Available in sizes to accommodate even the largest motor shaft diameter, PRO Series shaft grounding rings come in mating halves to facilitate field retrofits on coupled equipment. With multiple rows of conductive microfibers completely surrounding the shaft, they provide millions of discharge points for harmful shaft currents and are ideal for high-current motors controlled by variable frequency drives (VFDs), including low-voltage motors over 500 HP, medium-voltage motors, power generators, and OEM systems.

    If not diverted, VFD-induced high-frequency shaft currents and circulating currents discharge through motor or generator bearings, or through coupled equipment, causing severe electrical damage.  Bearing failure and catastrophic generator/turbine failure can result in as little as 6 months. Compatible with current-monitoring equipment, AEGIS® PRO Series Rings encircle the motor shaft with patented microfibers, providing a path of least resistance to ground and effectively diverting these currents away from bearings.

    AEGIS® PRO Series Rings are the longest-lasting and most effective shaft grounding system available today. Engineered to handle high frequency shaft currents up to 100 MHz, they can be installed as part of a preventive maintenance program whenever bearings are replaced.
