ME-PROT 403: Distribution System Protection


This course is designed for engineers who need a comprehensive understanding of the challenges and solutions for protecting medium-voltage, utility-type distribution systems.

PROT 403 provides an overview of the principles, schemes, and devices for protecting medium-voltage distribution feeders and buses. The course provides basic guidelines for overcurrent device coordination in radial systems. It also covers the application of negative-sequence overcurrent and directional overcurrent protection in distribution systems. The course discusses the effect of load and distributed generation sources on protection. It also provides guidelines for fast service restoration in distribution systems.

Note: This course teaches fundamental knowledge but does not provide hands-on experience with SEL relays.

Course Objectives

At the conclusion of this course, students can:

  • Identify the challenges and solutions to medium-voltage distribution system protection problems.
  • Describe distribution system protective devices.
  • Select and calculate settings for distribution system protective devices.
  • Identify and apply negative-sequence overcurrent protection in distribution systems.
  • Explain the effect of load on distribution system protection.
  • Identify, apply, and calculate settings for distribution bus protection schemes.
  • Describe methods for fast service restoration in distribution systems.
  • Identify protection practices and regulations of distribution systems with distributed generation.

Course Requirements

A degree in electrical engineering or equivalent experience is required. In addition, PROT 403 requires completion of PROT 401: Protecting Power Systems for Engineers or the following:

  • A basic knowledge of power systems and power system protection
  • Familiarity with medium-voltage distribution systems
  • A working knowledge of ac three-phase electrical circuits, trigonometry, basic calculus, complex numbers, and phasor concepts

Recommended reading: We recommend any power system analysis book of your choosing that covers per-unit quantities, symmetrical components, and fault analysis.
