ECE 4354 Power System Protection | ECE | Virginia Tech

Undergraduate PROGRAMS

Course Information


Protection of power apparatus and systems. Fuses. Voltage and current transducers. Relays, Coordination of Relays. Pilot channels. Grounding practices. Surge phenomena. Insulation coordination.

Why take this course?

This course covers the subject of protection of power systems against faults and transient overvoltages. It is supported by a concurrent laboratory where related experiments are performed. Together, these two courses will provide the students a comprehensive treatment of the theory and practice of relaying. Also surge phenomena and protection practices against surges will be covered in this course.

Technical Elective


C- or better in 4334

The concepts of power system analysis developed in EE 4334 are essential for the understanding of power system protection taught in this course.

Major Measurable Learning Objectives

  • Analyze the performance of power system transducers
  • Apply the fundamental principles of power system protective devices.
