Module goal - Knowledge and skill to be achieved by students
  Students are to acquire knowledge and skills that will enable them to understand what to do, when to do and how to interpret results of applying new technologies during on-line and off-line diagnostic testing of components of the EPS (transformers, switches, SF6 systems, cables, insulators, surge arresters) for the purpose of making optimal decisions related to their maintenance.
<br>
The course is designed to present students with typical faults and aging parameters that apply to different components of the EPS, after which they will be able to discuss the most widely used on-line and off-line tests for monitoring conditions of those components.
<br>
At the end, the course will focus on results' interpretation and application of computer-supported tools which are used in the planning of maintenance activities, primarily based on reliability (RCM).
<br>
After successfully completing the course the student will:
<br>
- be able to understand the function of maintenance and its effect on the company's profitability
<br>
- be able to design a long-term plan for maintenance of electronic equipment
<br>
- understand the ability of modern information systems to transfer and process informations related to maintenance
<br>
- understand mechanisms that lead to structure deterioration of electronic equipment
<br>
- be able to measure level of intensity of important mechanisms and to use obtained information for determining conditions of the equipment and to undertake the required maintenance regimes;
<br>
- be familiar with application of different monitoring techniques (oil analysis, measuring intensity of acoustic, electric, mechanical and thermal effects) for the purpose of equipment evaluation and carrying out necessary maintenance activities
<br>
- be able to process and analyze data so as to improve performance and minimize maintenance costs.
<br>

Syllabus
  1. Introduction to the maintenance of electrical equipment: conditions data, the failures statistics, reliability modeling techniques, reliability estimation tools, maintenance planning tools, maintenance planning systematic techniques, preventive (time-based maintenance and maintenance based on the equipment conditions) and corrective maintenance.
<br>
2. Standard failures pertaining to the EPS components (cables and cable accessories, switches, transformers ...)
<br>
3. Monitoring and diagnostics of failures on different components of EES
<br>
- Monitoring methods: electric, acoustic, electro-optical mechanical and thermal sensors
<br>
- Analysis of noise carried by fluid, air, structure
<br>
- Signal processing: spectral analysis, time line analysis
<br>
- identification of failures
<br>
4. Expert systems and real time analysis: data acquisition, interface...

Didactic methods
  Course lessons are taught by the professor in lecture halls, and followed by demonstration and solving of practical examples and mathematical equations/graphs. Additionally, students spend time on tutorials and lab-exercises. They resolve specific problems pertaining to their theses, using available or student-developed software. Goal of these activities is to enable students to get hands-on, practical experience in this area, as well as to gauge students' knowledge through assigned papers and exams (mid-term, as well as final).
<br>

Exams
  During the course students earn points according to the following system:
<br>
- Attending classes and tutorials: 10 points; a student with more than three absences from lectures and/or tutorials will not be eligible to get these points.
<br>
- Home assignments, laboratory reports and/or final thesis: maximum of 10 points.
<br>
- Mid-term and final exams: a student can score up to 20 points on each exam (passing grade is 10 points).
<br>
During each of the two exams (time assigned is 90 minutes) students will solve simple questions - designed to examine whether students acquired basic theoretical knowledge –multiple choice problems, as well as one open-answer problem. Students who gain less than 20 points during one semester must re-take that course.
<br>
Students who earn 40 or more points during the semester are eligible for taking a final exam; the exam asks the student to discuss mathematical problems from the mid-term exam and home assignments, as well as to answer to simple questions related to general course topics.
<br>
A student can score a maximum of 40 points on the final oral exam (passing threshold is 20 points). A student who gets less than this minimum, must take a makeup oral exam.
<br>
A student who earns 20 points or more, and less than 40 points during the whole semester will have to take a makeup exam. The makeup exam is organized in the following manner:
<br>
- Written part is structured similarly to mid-term written exam, during which students will have to solve problems in which they failed on their mid-term exams (got less than 10 points).
<br>
- Oral part of the exam is structured in the same way as the oral part of the final exam.
