Design Project
A project relating to design of protection system for a small power system will be
assigned for this class. The students will be required to submit a formal report after
completion of the project.
Exams
There will be two semester exams and a final exam. The dates of the
exams are mentioned elsewhere in this handout.
Grading
The grades will be decided on the following basis:
Exam #1
Exam #2

Scores of 90, 80, 70, and 60 will be used as a guideline for determining A, B, C and D
grades. However, the grades may drop by a few points depending on the nature of the
exams.
Email
A listserve (eece686-l) will be setup for all communications related to this class. All the
students must use it for communication related to the class as much as possible.
However, for personal matters you may send the email directly to me.

Minimum Standards for Student Papers
Most engineering organizations have internal standards for their drawings and
documentation. The purpose of these is to facilitate the exchange of information and to
reduce unnecessary work. The following simple standards will apply to all student
papers including homework, quizzes, and computer programs.
1. Student’s name, instructor’s name, course title, date, and page number to appear on
the top of the first page. Include a title when relevant.
2. Student’s name, date, and page number to appear on all other pages.
3. Cut and trim all computer printouts to proper size.
4. If the pages require stapling, staple in upper left corner.
5. Use engineering paper for all work unless requested otherwise. Padmaster No. 34520
with the faint blue grid makes excellent photocopies. Use one side of the paper
only, unless specifically instructed otherwise.
6. Use a straight edge for all straight lines and a logic template for all symbols.
7. Work logically and systematically through your problems, show all important
steps. Answers without supporting work are not acceptable.
8. Box intermediate and final results giving all dimensions or units.
Example:
SLEW RATE = 100 Volts/Second
9. For design problems, when asked to explain how a particular system operates, you are
expected to provide the following:
9.1
A block diagram or circuit diagram;
9.2
Description of system operation with relevant equations;
9.3
Waveforms wherever possible;
9.4
Algorithm in English if applicable.
