FEKT-CUEEAcad. year: 2019/2020
Utilization of electricity is realized in a number of technological processes and is immediately linked with its consumption. The electrical energy is used in different processes such as heating, cooling, illuminating, transportation, information generation and transmission, etc. The course makes students familiar with basic types of electrical appliances differentiated to electronic devices, light sources, electro-heat devices and electrical drives with a view to typical design, performance, characteristics of consumption, etc. From point of view of electricity use, the course is focused on electro-heating and lighting engineering. In the part dealing with electro-heating, physics of the heat in context is recapitulated. Next, basics of electro-heating methods and related industrial and household applications are discussed. In the field of illumination, principles and properties of electrical light, light sources, luminaries, photometric quantities and units and artificial illumination from point of view of design, operation and maintenance are covered.
Learning outcomes of the course unit
Student is able to:
- describe individual load types from point of view of consumption characteristics and input power components,
- present basic topologies of power supply units and describe their behaviour,
- explain principles of the light generation, and derive basic spectro-radiometric and photometric variables.
- describe design and operation of the light sources dedicated for general illumination (incandescent, luminescent – discharge and LED lamps), including all ballasts/converters providing feeding in all operation states,
- evaluate light-technical and electrical parameters and properties of the light sources and consider their application,
- describe functionalities of luminaries, their properties and parameters used for sorting procedure related to applications,
- discuss approach of lighting systems design, apply individual procedures of design, including validation technique,
- specify basic types of electro-heating and discuss their applicability in industrial processes,
- explain principles, properties, devices, performance and utilization of direct and indirect resistance heating, arc heating, and induction and microwave heating,
- describe AC and DC traction system, including individual subsystems and their operation with a view to power consumption.
General knowledge in electrical engineering and physics at the level of second year of study and basic knowledge of material properties, power electronics and electrical machines and apparatus is expected.

Planned learning activities and teaching methods
Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations. Techning methods include lectures, numerical exercises and practical laboratories. Course is taking advantage of e-learning (Moodle) system.
Assesment methods and criteria linked to learning outcomes
There are evaluated of laboratory exercises, individual project and final exam according to the rules of FEEC. Laboratory training is rated at maximum of 30 points on the basis of submitted records, whereas 15 points is the minimum for admission to final exam. The individual project is classified by 10 points maximally. The final exam is composed of written and oral part, where 60 point can be acquired maximally from both parts (40 and 20 points respectively) and successful pass is conditional on obtaining 20 points in sum at minimum.
Overall classification of the course is in compliance with the FEEC rules. Requirements for completion of the course are specified by a regulation issued by the lecturer responsible of the course and are updated for every year.
The final exam is aimed at understanding in the field of principles and ways of electricity consumption, design of electrical appliances, consumption characteristics and applications mainly in electro heat and illumination engineering.
