ABSTRACT
The article reports on the installation of an AEGIS SGR Bearing Protection Rings from Electro Static Technology in the Time & Life Building in New York City. The article notes that the building's maintenance department had to deal with shaft currents caused by variable-frequency drives (VFDs) before the ring was installed. It reports that the ring causes motors to run quietly, run at cooler temperatures, and lowered shaft currents.
