This program will be presented in two (2) “live” half-day sessions on December 3 and 4, 2024. All sessions incorporate high-quality presentations by qualified instructors with Q&A and other opportunities for group interaction.
You will receive print copies of the presentation materials in advance, allowing you to work with them before, during and after the online sessions. The scheduled online sessions will also be recorded and available for a period of thirty (30) days, enabling participants to work around any scheduling conflicts.
Participants completing this program will receive seven (7) Professional Development Hours (PDH).
The registration fee for Introduction to Distribution System Overcurrent Protection is: $550 per person with a reduced group registration fee of $500 per person for any organization that registers three (3) or more people. Each participant from a participating organization is required to be a paid registrant. No group viewing is permitted unless all participants are registered.
Program Overview
Utility distribution systems are exposed to a wide range of events that can cause temporary overload and fault (short circuit) currents. This short course introduces and provides an overview of the approaches and equipment used to protect distribution system components from damaging overcurrent conditions. Topics include types of short circuit currents and their determination, the role of system grounding, overload and short-circuit current limits of distribution components, characteristics and typical applications of overcurrent protective devices, and selective coordination of devices for circuit protection.
