Graduates of this course should be able to
- characterize the basic types of electrical susbstation,
- apply appropriate arrangement of busbar systems of switchgear in the electrical substation project,
- select the appropriate power output and power transformers for substation,
- apply the basic interlocking conditions for the blocking of individual devices in switchgears branches,
- distinguish the devices in individual level of substation automation system,
- describe and explain the transformer protection system,
- calculate the setting of transformer differential protection,
- check power line according to thermal and dynamic effects of short-circuit current,
- design a grounding of transformer station according to the required earthing resistance.

The basic knowledge of the design of power lines, schemes and versions of switchgears in electrical substation are required. Students registered in the course should be able to describe and explain the principles of operation and equivalent circuit of transformer. Their orientation in the basic principles of functional types of protection is assumed. General knowledge is required at the level of bachelor's degree, but it is advisable to have completed courses Electrical Power Distribution and Distribution Equipment.

Techning methods include lectures, computer laboratories and practical laboratories. Course is taking advantage of e-learning (Moodle) system. Students have to write two projects/assignments during the course.

Students can obtain up to 50 points of the overall evaluation of the course during the semester - 20 points for projects up to 10 points for the processing of laboratory protocols and 20 points in the final test. A student has to obtain at least half of the maximum points in all mentioned activities.
The final exam is oral (max. 50 points). It focuses on the orientation in the topics as are defined in course syllabus. The condition for the successful passing this exam is to get at least half of the maximum points

The aim of course is to familiarize students with the current state of electrical equipment stations especially at medium and high voltage, with emphasis on operation and protection of transformers. Furthermore, to give information about the current substation automation systems. To give a comprehensive information about the theoretical foundations of designing of switchgears and conductors.

Labs are compulsory; correctly excused absence can be replaced by arrangement with the teacher.
