Catalog Description:
ECE 7337: Industrial Power System Protection - Cr.3. (3-0).
Prerequisites: ECE-6368 or ECE-6378 and Consent of instructor. Protection tasks, requirements, principles,
components; instrument transformers; protective systems: transformers, feeders, generators, motors, primemovers, buses, switchgears, cables, transfer devices, bus-ways/bus-ducts, UPS, service supply lines and utility interties protection schemes; components, operation, faults, testing, maintenance, calibration.
Objective:
Course introduces participants to the aspects of power system protection from the foundation of protection
principles to the industrial system level in framework of US regulations (ANSI, IEEE, and NEC.) Course consists of theory and applications. The theory follows required textbooks (see Text). The applications are implemented in MathCAD / MS-Excel and readily available configuration software for protective devices discussed in class.
Course Topics:
- Prerequisite material brief review: time waveforms, complex vector representation and sampling. Power
system equipment, apparatus and related basic calculations; modeling for load flow and short circuit
calculations; per unit system calculations for single and 3-phase; symmetrical components, fault analysis
principles and calculations for single faults. Conversion single phase loads to 3-phase equivalents. Load
flow (LF), short circuit (SC) and ANSI short circuit (ANSI-SC), device evaluations (DE), component
selection based on LF, ANSI-SC and DE.
- Engineer’s legal, ethical responsibility as related to system protection. Engineering protection
documentation, symbology and “industry standards.”
- Introduction to protection, protection tasks requirements and principles. Protective devices, components,
types, functions, and applications. Past, present and future. Electrical metrology and transducers as related
to protection. DSP technology applications and influence on protection and metrology.
- Current and voltage transformers principles, classification, selection and application for protection
application.
- Discussion of following protective systems:
o Radial feeder, bus-ducts, cables, distribution line protection
o Transformer protection
o Induction, synchronous and DC motor protection
o Synchronous generators and prime movers (diesel and gas engines, turbines)

Homework:
Homework assignments are distributed on weekly basis. Homework should be submitted via email and due date for homework is Tuesday of the following week at 7:00 pm. Late assignments are not accepted.
Grading Policy:
The course final grade will be determined based on submitted homework, exams, and project grades with the
following approximate weights. The actual weight will be fixed at the end of the semester.
Class participation: 10%
Homework: 15%
Midterm and Final exams: 40%
Term project: 35%
• Class Participation: We expect you to participate actively in class discussions, contribute your own ideas and comment on the ideas of others. The readings if assigned should be done before class. In class, we will call on you and ask you to answer questions about the readings and to contribute to the discussion (reading
assignments are part of Homework grade).
• Term Project: You will be required to do a term project, leading to a final report. You are expected to work in teams. This will be a major project, and you should expect to devote your time to it throughout the semester.
• Oral Term Project Status Presentation: You will be required to make an oral presentation on your project, both final report and a progress reports (part of Term Project grade).
• Midterm Exam: There will be in-class midterm exam.
• Final Exam: There will be in-class final exam.
Grade Point Rule:
The following approximate grade point scale will be used in determining your grade. This scale may be modified somewhat, but is included here so that you will have a general idea of how well you are doing in the course. The final grade scale will be determined at the end of the semester.
90 – 100: A’s 80 – 89.99: B’s 70 - 79.99: C’s 60 – 69.99: D’s below 60: F
Attendance:
Attendance at all classes is expected and required. The attendance will be part of your participation grade.
