The Zoom webinar service EASA uses will ask to install a small plugin. Your computer must be configured to allow this in order to have full functionality. Please check with your IT department or company's security policy prior to scheduling a private webinar.
EASA's private webinars are an inexpensive way to bring an EASA engineer into your service center, place of business or group meeting without incurring travel expenses or lost production time.
This session will address key issues related to shaft and bearing currents in electric motors and generators. Critical topics that will be covered include recognizing symptoms of shaft and bearing currents, and determining if damaging current levels are present. Also, possible causes of the damaging current, such as machine dissymmetry and operation on variable frequency drives (VFDs) will be dealt with. Methods of testing to confirm the presence of shaft or bearing currents will be described, as well as how to assess the magnitude of the damaging currents. Further, solutions to eliminate or control shaft and bearing currents, such as insulators, isolators, and ceramic bearings, will be offered.
Who should attend
This seminar will be most useful for service center and field technicians with at least 5 years experience, service center managers, engineers, or anyone with previous experience dealing with shaft and bearing current issues looking to expand their knowledge.
