Department of Power Systems and Control
Advanced research works are performed in the field of electrical engineering, mostly in electrical power engineering (generation, transmission and distribution of electrical energy). Specialists at the Department deal with the development and exploitation of Polish power systems, in particular the diagnostics of their high- and medium-voltage transmission lines, as well as the system reliability. Investigations of high-voltage insulating systems and high current paths are also carried out in the Department. Prosumer power engineering and diversification of electrical energy sources play an important role in the research. Properties of power network component elements and their reliability as well as the way they function under adverse conditions (contaminated environment) are tested. Scientific staff of the Faculty also performs modeling and simulation of disturbances of power system and its elements. The area of interest of the Department is optimal automation systems for detecting abnormal states in power system and its elements. The latest research focuses on identification of influence of high frequency electromagnetic fields on living organisms.
Department of Measurement Science, Electronics and Control
The staff of the Department conducts research on electrotechnical materials, wired and wireless measuring systems, control systems, measuring sensors and transducers, accurate electrical measurements and new electronic solutions in the field of measurement science. The Department scientists prepare expert research reports and opinions for industrial units and courts. The Department is a national leader in construction of the national AC voltage standards. The first primary AC voltage standard has been developed by the Department researchers. One of the latest achievements of the Department is the creation of a new laboratory of AC DC standards with a stand for thermal comparisons of AC voltage transfer standards with the highest accuracy attainable in the world.
Department of Electrical Engineering and Computer Science
Research conducted in the Department covers various aspects of modern electrical engineering, electronics, signal processing and computer science.

The technological offer developed by the employees of the Department of Mechatronics also includes several projects that can be used for further development by industrial partners. Those are:
Electromagnetic generator of torsional vibrations
The developed prototype of an electromagnetic torsional vibration generator is a structurally modified induction machine. It uses the higher harmonics of the magnetic field in the air-gap to produce torsional vibrations. The electromagnetic torsional vibration generator can be used to identify the natural frequencies of complex drive systems.
Rotary-linear induction motor
The developed prototype of the engine is a completely Polish design made on the basis of engine components mass-produced by a domestic manufacturer of electric motors. The solution uses innovative solutions to achieve better dynamics of the drive system while maintaining the dimensions of a mass-produced engine.
We design and manufacture electromagnetic shakers. Our shakers are specifically made direct current motors excited by permanent magnets, with a limited range of linear motion. The designed shakers are used to generate axial vibrations in various directions.
