Course detail

Safety of Electrical Devices

FEKT-MPC-BEZAcad. year: 2025/2026

The course is an introduction to the issue of safe operation of electrical medical devices. Students will gain knowledge of the principles, legal provisions, safety regulations and technical standards in the field of safety in electrical engineering. Particular emphasis is placed on the specifics of medical equipment and the potential electrical and other risks, which may occur during their operation.
The course prepares students for the examination in accordance with Act 250/2021 Coll. and NV 194/2022 Coll. on professional competence in electrical engineering. After a successful examination before a committee (optional part of the course), graduates will obtain the qualification of an independent worker.  The course prepares students for the examination cin acordance with Act 250/2021 Coll. on professional competence in electrical engineering and the related NV 190/2022 and NV 194/2022 Coll. After a successful examination before the commission (optional part of the course), graduates will obtain the qualification of a person knowledgeable for independent activity.

Department

Department of Theoretical and Experimental Electrical Engineering (UTEE)

Entry knowledge

The student should be able to:
- apply Ohm's law and Kirchhoff's laws in single-phase and three-phase circuits;
- explain the concepts of circuit analysis in harmonic steady state (e.g. impedance, effective and mean value).

Rules for evaluation and completion of the course

The evaluation of the course is based on two written tests: 0 - 40 points from the control test and 0 - 60 points from the final test. If the student obtains 75% of the possible points from each test, he/she can optionally take an oral examination before the commission to obtain a Certificate of Professional Competence in Electrical Engineering according to § 6 of the NV 194/2022 Coll. - a knowledgeable person with higher qualification for independent work on  electrical equipment up to 1 000 V. 


Attendance at given lectures is mandatory for those who wish to obtain a certificate of proficiency in electrical engineering (after exam before commissions).

Aims

To learn the principles of safe design and safe operation of electrical medical equipment as part of professional erudition. Indicate the specific requirements of medical installation and equipment, to highlight the potential risks in the operation of diagnostic and therapeutic medical devices.
After completion of the course student will be able to:
- explain and apply the principles of protection against electric shock,
- explain protection against overloads and short circuits, and protecting against surges,
- define protection againts the effects of fire from electrical equipment,
- describe and identify possible electrical and other risks associated with the operation of medical electrical devices,
- apply first aid in case of electric shock including use of AED.
Optionally, students may graduate to qualify for independent work on electrical medical devices in terms of safe work and safe operation.
