Who Should Take This Course 

• FIU Electrical and Computer Engineering Students who took EEL4213 (power I) and Graduate Students.

• Students at other Universities in Florida or out of State with the course’s prerequisites.

• Engineers and technical personnel in Industry preparing for Engineering License

• Engineers and technical staff who want to keep current and reach a deep understanding of energy conversion concepts.

Objectives

1. Introducing Electrical Transients in power systems

2. Cover the concepts of traveling waves and propagation

3. Modeling of transmission lines as distributed parameter systems.

4. Discuss issues related to insulation coordination, grounding and limiting of surge effects

5. Develop techniques related to reflections at transition points in lines and cables

6. Multi conductor transients and distributed parameter modeling for components and shielding issues.

7. Involve students in a practical experience through the term project.

Appropriate lists and copies of technical papers will be distributed or listed for your collection. A list of Recent text-books

and other technical record will be suggested to you. However, your are also required to research and obtained other pertinent

materials related to the topics covered.

ASSISTANCE

Please try to see Dr. Mohammed during his listed office hours or through the communication forum on the web page. If this proves impossible, a personal appointment should arranged by calling calling my direct phone number or the ECE department secretary at

extension (305-348-2807).

ABSENCE 

Class attendance (physical or virtual) is very important and is considered in your overall performance in the course. Students are

responsible for all material covered in that class.

IMPORTANT RULE

Students are encouraged to discuss the course topics with the professor and with each other. Any work submitted (Homework, Tests, projects, etc.) should be pledged and signed as the students' own work, and that there is no any unauthorized help was obtained.

Violators will be subject to academic misconduct, which might lead to dismissal from the university.

GRADING POLICY 

Homework will be assigned regularly, collected and graded. Efforts in homework indicate that you are studying and caring about the

course and therefore can have an impact on your final grade.  Time for the mid-term will be announced one week in advance.  Any work submitted must be neat and detailed for partial mark. Your Grade will be calculated as Follows:

TERM PROJECT

A good practical experience. During the semester you will be assigned a design project on the basis of a RFP (Call for Proposals). The project will involve one or more of the topics of this course. Final presentation (oral and written) of the overall project results will be

required. Software available for this class can be utilized for the projects.
