Department of Power Supply, Electrical Installations and Electric Transport” acquired its current form in 1997, following the merger of the Department of “Power Supply and Electrical Installations” (1983). In previous years, the current department was part of the Department of “Electric Power Plants, Networks and Systems” established in 1946 and the Department of “Electric Transport” (1960).

The current department has four main training directions: power supply, electrical installations, lighting technology, and electric transport.

The main teaching directions cover a wide range of topics in the field of electrical engineering and energy.

Among them, special attention is given to the power supply of industrial enterprises. Another important part is the electrical installation of machines, facilities, and technological processes. Lighting and installation technology also have significant importance. In this regard, work is actively carried out on issues of energy efficiency.

Attention is also paid to the quality of electrical energy. An important part of the activity is related to the optimization of power supply systems. No less significant is the technical operation of electrical installations. Subjects such as renewable energy sources are gaining increasing importance. The application of microprocessor systems for the control of facilities and technological processes is also among the department's priorities. Research is also conducted here in the field of identification of power systems.  

Special attention is given by the lecturers to light sources and starting and regulating devices. New solutions for luminaires and floodlights are being developed. Light guide systems for lighting are also applied. Students here can learn how to properly design solutions for decorative and advertising lighting.
Work is also being done to improve the efficiency of indoor, street, tunnel, floodlight, and special lighting installations.

Additional attention is given to the power supply and electrical equipment of electric transport. In this direction, the capabilities of traction substations and contact networks are being studied and improved.

The department carries out a number of expert, consulting, research, and engineering activities in support of society.

The department is responsible for the educational process of the specializations "Power Supply and Electrical Equipment", "Lighting Technology", and "Electric Transport" from the broad-profile specialization "Electrical Engineering and Electrical Equipment", with educational and qualification levels of "Bachelor" and "Master". Students from the specialization "Electric Energy from Renewable Energy Sources" are also trained here, at the "Master" educational and qualification level.

The department provides training in general 48 academic disciplines. Student training is carried out in 10 teaching laboratories. Over the last 30 years, more than 2000 Bulgarian and around 250 foreign electrical engineers have graduated in the field of "Power Supply and Electrical Equipment of Industrial Enterprises", and in the field of "Electric Transport" - more than 300 electrical engineers. 

Under the supervision of department members, over 30 doctoral dissertations have been defended in the fields of "Power Supply and Electrical Equipment of Industry and Transport" and "Lighting Technology and Light Sources". Faculty members and doctoral students from the department also develop applied systems in the "Scientific Research, Testing and Calibration Laboratory for Lighting Technology".
