DESCRIPTION

The training in the principles and methods used to perform protective device coordination studies for low voltage through distribution level power systems with or without software. This is one of the few courses that is not merely a software training course. Specifically designed for industrial and government engineers that want knowledge of the principles of protective device coordination but also practical knowledge of how to achieve reasonable and economical device coordination.

The only course which can cover both national codes and standards and government criteria that affect coordination philosophies. Covers concepts, procedures, and guidance not covered in other courses in the industry. Examples will include critical systems fed from emergency generators and uninterruptible power supplies (UPS).

WHO SHOULD ATTEND

Utility engineers, consultants (especially those involved with IPP/DG design), equipment/control engineers, generator packager and manufacturer engineers as well as others who specify protective relays and develop settings for these devices.
