EEM 414 - Protection Systems in Electrical Installations

Faculty of Engineering and Natural Sciences · Electrical & Electronics Engineering (English 30%) · Undergraduate

ECTS: 5 T+P+L: 3+0+0 Departmental Elective
Coordinator: Doç. Dr. Mohammed VADİ

Course Objective

The main goal of the course is to provide a general overview of principles and schemes for protecting electrical lines, transformers, substations, and generators. It also briefly introduces international protection codes based on IEC and IEEE. The course provides fundamental guidelines for relay protection and setting calculations, examining power system faults, and instrument transformers. Throughout the course, students will gain skills in calculating settings and testing protection operating conditions.

Course Content

The course's main objective is to provide an overview of the principles and schemes for protecting power lines, transformers, buses, and generators. It also briefly introduces international protection codes based on IEC and IEEE. The course provides basic guidelines for relay protection and setting calculation. It also reviews power system faults and instrument transformers. Throughout the course, students will be able to get skills for calculating settings and testing protection operation conditions.

Explanations

Explanation of Assessments

There will be in-class weekly quiz, in addition to one midterm exam, and final exam.

1.Most quizzes will be pre-announced at least one lecture in advance. No make-up quizzes will be given.  However, the lowest quiz will not be counted toward your final grade.

2.Exam dates are shown in the previous mentioned table.  Refer to the syllabus to see the topics that will make up the material for each exam. With a valid written excuse and making immediate arrangements with the instructor, a missed exam might be replaced with the grade of the final exam and/or the average grade of all tests (including final) and/or quizzes.

3.The final exam is comprehensive.  The date and time of the final exam will be scheduled by the registrar’s office.

 

Rules

Student Academic Integrity Code Statement

Student must adhere to the Academic Integrity code stated in the 2022-2023 undergraduate catalog.

Remarks and Rules

  1. Attendance: It is the university policy that attendance is compulsory.  A student missing more than 25% of the total allocated course hours will receive a WF (Withdrawal While Failing).
  2. Getting Help: Students are encouraged to consult their instructor during office hours, or by appointment. However, before seeking help from anyone, make sure you read your lecture notes and textbook. See the examples similar to the problem in question then try to do the problem yourself. It should be emphasized that students who miss a class without a valid written and/or legitimate excuse will not be offered a one-on-one lecture discussion during office hours to substitute the missed class.
  3. Academic Misconduct will not be tolerated.  You are expected to submit your own work. Copying, cheating or plagiarism, when detected, will result in an FF grade in the course for all who are involved (i.e. it does not matter if somebody copied your homework, project etc., you are guilty as well).

The Istanbul Sabahattin Zaim University affirms the importance of integrity and respecting the work of each individual.  As an institution of higher education, the university views academic integrity as an educational as well as judicial issue.  Academic violations include (but not limited to) the following: plagiarism, inappropriate collaboration, dishonesty in examinations, dishonesty in papers, work done for one course and submitted to another, deliberate fascination of data, etc. See the Student Handbook at http://www.izu.edu.tr/handbook/ for more details.
