    Synopsis of lectures

    There is no lecture in this subject.

    Synopsis of practice and laboratory occasions

    1.     Impact of consumers on the network in building energy systems

    The aim of the measurement is to point out the effects of different consumers that distort the voltage and current curves, generating harmonics.

    2.     Electro-adhesion test

    Students will learn about the phenomenon of electro-adhesion in practice. The dependence of the gripping force on electrical parameters and material properties is investigated on an electro-adhesion gripper.

    3.     Testing synchronous and asynchronous machines - testing switching transients

    During the measurement, students will learn about low-power synchronous and asynchronous drives and motors, which are also used in building services systems. During the measurement, the characteristics of the motors are recorded and compared from a dynamic and application point of view.

    4.     Investigation of innovative electromechanical converters

    During the laboratory exercise, students will learn about basic piezoelectric phenomena. The electrical and electromechanical characteristics of a piezoelectric converter are investigated, and its characteristics are plotted.

    5.     Switching on and off DC and AC circuits

    Students will measure various distributed-parameter circuits for on-off and on-off transients. The purpose of the measurement is to make the student aware of the effects of switching overvoltage and the process of their generation.

    6.     Investigation of electric arc characteristics and interruption

    Students will be introduced to DC and AC arcs. During the measurements, they will take characteristics of the arc-interruption process and compare them with what they have learned in theory.

    7.     Testing the operation of fuses and circuit breakers

    Students will learn about the different protection systems of low voltage networks, such as circuit breakers and fuses. During the measurement, they will record their characteristics and examine the devices in operation.

    8.     Insulating and dissipative materials. Design of an electrostatic workplace.

    Students will learn the principles of designing electrostatically protected workplaces. They will verify the electrical properties of the materials used and the effectiveness of protective measures against electrostatic charging by measurements. 

    9.     Testing thermoelectric converters  

    The aim of this laboratory exercise is to familiarize students with thermoelectric converters. The electrical characteristics of a thermoelectric converter and the efficiency of the conversion are measured.

    10.  Insulation testing methods based on partial discharges and reflectometry

    Students will perform electrical measurements on a current transformer to detect partial discharges. In the second half of the measurement, reflectometric tests are carried out to determine the fault location in cable systems.

    11.  Generation of high voltage

    Students will learn and measure methods of generating different voltage levels, both DC and AC.

    12.  Physics of induction heating, the forces caused by electric current

    In this laboratory occasion, students will study the technique of induction heating, measure the efficiency of the conversion and determine the electrical parameters of the system.

    9. Method of instruction The subject consists of 12 laboratory measurements, once a week.
    10. Assessment

    Preparation for the measurement based on the measurement guide.

    Participate in the measurement at the time and location scheduled by the Course Coordinator.

    Only those students who have the subject knowledge required for the readiness check can take part in the assessment.

    Preparation and submission of a common or individual report by the deadline.

    All assessments are graded (based on answers, performance in the assessment, report). To obtain a semester-end signature, all measurements must be passed with at least a satisfactory level. The mid-semester grade is calculated by rounding the average of the grades given for each assessment exercise.
    11. Recaps Two laboratory measurements can be repeated during the semester. Recap opportunities will be provided during the Week of repeats.
    12. Consultations Specific consultation sessions will be arranged on the basis of the student's request and by appointment.
    13. References, textbooks and resources For each laboratory exercise, electronic measurement guides are provided and can be downloaded from the course Moodle site.

    IMSc program

    In the assessments, IMSC points may be earned by solving an additional assessment task beyond the normal requirement, if the student has achieved mark 5 without these points.

    If a student has earned IMSc points in an assessment, it is not possible to increase the IMSc points by re-doing that assessment.
    IMSc score

    The maximum number of IMSc points can be earned is 25.

    IMSc points can be earned by students in the assessments. A maximum of 2 IMSc points can be earned on each assessment.

    IMSc points can also be earned by students not participating in the programme.
