manufacturers and users of should strive to protect the as well as their windings. the following measures have proven effective under actual operating conditions and should be considered for inclusion in any standards updates:
for motors above 100 hp, in which both circulating currents and common-mode voltages can cause bearing damage, an insulated bearing on one end and a shaft-grounding ring on the other provides the best protection from .
for motors 100 hp and less, adding a either inside of a motor or externally effectively protects bearings and attached equipment from currents.
