LEA

Laboratory of Electrical Engineering and Automation

WHAT IS DONE AT LEA?

The Laboratory of Electrical Engineering and Automation (LEA) has adopted the mission of two former laboratories: the Electrical Engineering Laboratory established after the 1962 relocation of the Maritime Junior College to the present location, and the 1974 Laboratory of Technical Measurements. 

 

In laboratory tutorials for first- and second-cycle degree study programmes, all students gain hands-on experience in dealing with electricity, communication and navigation electronics as well as automation. Numerous students’ degree theses are based on the results of the work done in LEA (D. Loredan, D. Kocjančič, M. Oblak, S. Prešeren, I. Hrastnik). Cooperation with other institutions within the University of Ljubljana (especially the Faculty of Electrical Engineering and the Faculty of Civil Engineering and Geodesy) and abroad (currently, we are actively collaborationg with EC-JRC, Ispra), is expected to result in interesting research work and relevant research results.
