If you are unable to attend at the scheduled date and time, we make recordings available to all registrants for three business days after the event

The Advanced Overcurrent Protection course provides attendees with a review of Symmetrical Components and moves to Fault Current Calculations using the Per Unit Method. The course covers design options of Three Phase Reclosers and Circuit Breakers. Attendees will gain an understanding of ground fault protection and other protection schemes. We recommend attendees bring an engineering calculator to class. The training will utilize practical examples to enforce the classroom concepts. The training is focused on the technical engineering protection issues, not any specific manufacturer’s equipment or device.

Learning Outcomes

  • Discuss calculation of fault currents using the Per Unit method
  • Review circuit breakers, three phase reclosers, IntelliRupter
  • Discuss protective relays
  • Discuss the coordination of overcurrent protective devices
  • Review self-healing systems
  • Assess padmount switchgear design options
