ELECTROTECHNICS I

Course Unit Content:

Magnetic fields. Permanent magnets and electromagnetic magnets. Magnetic field: graphic view,

types, direction. Electromagnetic induction laws. Self-inductance. Lenz’s law. Mutual induction,

mutual inductance, faktor veze, transformers. Alternating current and voltage. General about

variables: referent directions, graphic view, momentary values, waveforms. Parameters of

alternating current and voltage. Symbol calculations. Use of complex calculations in solving

alternating network, types of complex numbers. Multiphase systems: definition, genesis, graphic

view, unconnected three-phases system. Symmetrical system in the Y-connection, phases and lines

variables, connection in triangle. Non-sinusoidal variables: definitions, beginning, analysis of

frequency. Definite fields: electric-power supply, electrical device.

Computer exercises by simulation program. Creation of project.

Exercises 70%, lab works 30%.

Exercises are numerical and follow lectures. Lectures include the use of sophisticated computer

programs. Lab works are performed in a real laboratory. The realization of exercises is described in

the lab sheets. They also include all needed explanations and conclusions.
