Electric Distribution Three-Phase Overcurrent Protection

September 22 - 23, 2026 Online :: Central Time

“Great course for beginners in the energy industry, just enough to not overwhelm with information.” 

Journeyman Meterman / Substation Technician, West Oregan Electric Cooperative

The Electric Distribution Three-Phase Overcurrent Protection course provides attendees with a review of Symmetrical Components and moves to Fault Current Calculations using the Per Unit Method.

Attendees will gain a wealth of information including:

  • Design options of Three-Phase Reclosers and Circuit Breakers
  • Ground fault protection and other protection schemes
  • Circuit breakers, three-phase reclosers, IntelliRupter
  • Coordination of overcurrent protective devices
  • Padmount switchgear design options

The training is focused on the technical engineering protection issues, not any specific manufacturer’s equipment or device and will utilize practical examples to enforce the classroom concepts.

 

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

Instructors

Martin T. Bishop (IEEE Member 1978, Senior Member 1988) received a BS and ME in EPE from Rensselaer Polytechnic Institute in Troy, NY. He also completed an MBA at the Keller Graduate School of Management. His first position was with Westinghouse in Pittsburgh, PA in the Advanced Systems Technology division. He was the lead engineer on a project to develop new protection systems to detect fallen distribution conductors. Marty worked for 20 years in the Systems Engineering department at Cooper Power Systems where he supervised a group that performed industrial studies, power quality measurements and designed filter systems for large industrial plants. He also participated in the development and application of new relay protection systems using Rogowski coil current sensors. The work developed and applied the first differential protection systems for electric arc furnace transformers. In 2010, he joined S&C as a Sr. Marketing Manager within the Strategic Solutions Business Unit. His group focused on power system applications of STATCOM systems for renewable plants and general power quality
