IEEE PES: Distribution Overcurrent Protection and Coordination

Discover the principles of selective coordination, in which removal of faulted equipment and line sections – followed by system restoration – occurs both quickly and reliably. Learn how new technology protective devices can be applied to improve power quality. This three day course instructs attendees on the selection and application of overcurrent protective devices for use in medium-voltage electric power distribution systems. Throughout the seminar, attendees are given assignments to reinforce the concepts and procedures covered. Also, a comprehensive system protection and coordination example is developed, connecting many of the seminar topics. Software tools for simplifying the coordination process are briefly discussed and demonstrated.

Who Should Attend

Electric utility engineers, consultants, and others involved in the selection and coordination of overcurrent protective devices used in medium-voltage electric power distribution systems. Also, facilities engineers engaged in the selection of devices for protecting small power transformers, as well as the coordination of those devices with both source-side and load-side protective devices.
