High Voltage Laboratory

About the laboratory

The High Voltage Laboratory is situated in a common building with the Block “V1” of the University of Technology and Economics in Budapest. It has a 24.16 m x 16.26 m sized area with 386 m2 effective interior space, and its height is 16.45 m. The craned hall is designed regarding the required flash-over and breakdown distances to ensure safe operation of the highest voltage equipment in the laboratory. The installations that belong to the High Voltage Laboratory are the localized and the mobile high, medium, low and extra low voltage equipment inside the lab, the substation in open air next to the hall of the High Voltage Laboratory supplying the 600 kV test transformer, the line, the adapting and the regulator transformer and their parts (environment-friendly basement, protective wall, rainproof roof), their feed cables and couplers, as well as all of the equipment which protect and feed these. Furthermore other main equipment are installed on the ground floor of the Laboratory, which are supplied by the 800 kVA transformer and 0.4 kV switchgear.

In the history of the High Voltage Laboratory the first important equipment was a 250 kV transformer which is still in use. It was followed by the impulse generator which is capable of generating up to 1 MV peak value impulses. In the ‘70s the high voltage live line maintenance was introduced in Hungary, and at the same time the Laboratory was equipped with a 600 kV test transformer and with a 750 kV impulse generator. In the summer of 2012 the Laboratory was completely renovated. The largest Tesla-coil of Hungary is also located in the Laboratory.

The main workplace of Group of High Voltage Technology and Equipment of the Department of Electric Power Engineering of BUTE is located in the Block “V1” of the University of Technology and Economics in Budapest.


The BSc, MSc and PhD students of Budapest University of Technology and Economics, the participants of Institute of Continuing Engineering Education and experts of external companies are educated by Group of High Voltage Technology and Equipment.

Modular Hybrid Drive System Laboratory


The rapid spreading of electric vehicles generates a need for special power electronics equipment for testing the powertrain of such vehicles. Productive R&D activities of the last few years in cooperation with Siemens made it possible to build a modular hybrid drive system laboratory on the BME campus, co-owned with Rolls-Royce Hungary. With our special self-developed technology, we are able to perform tests on any part of the powertrain as well as on the full system in the 300kW, 1200V and 20000RPM range. Further improvement of the lab shall enable testing functionalities for any power electronics device beyond E-vehicles. Our mission is to meet the demands of industry by providing services of the highest quality.


For our partners, we provide extensive testing possibilities for complete powertrain systems and powertrain components like motors, generators, power converters, batteries and inverters among many others. With our special high voltage, high frequency and high power PHIL (Power Hardware In the Loop) system we are able to emulate rotating machines and various speed sensors with flexible customizable electrical and mechanical parameters. We can provide forced air cooling and liquid cooling solutions which fit most of the existing devices. With our automatic measurement and data acquisition system, it is possible to measure the voltages, currents, speed, torque and various temperatures of the tested device.

Industry 4.0 technology center


The Industry4.0 Technology Center (TC) was established by the Budapest University of Technology and Economics as a subcontractor of the IFKA – IVSZ consortium with funding from the GINOP 1.1.3-16 project (Model Factory Project). The TK was established as part of the BME FIEK, currently it is operated in the cooperation of the Faculty of Electrical Engineering and Informatics, Mechanical Engineering and Transport Engineering in a 260m2 area of BME Building I.

The main goal of the TC is to introduce the opportunities of using Industry4.0 technologies to as many Hungarian SMEs as possible and to provide practical knowledge for the implementation of an Industry4.0 investment. In addition to this, the main objective is to introduce the industrial digitalisation technologies and prepare students for their application. Thirdly, it is the mission of the TC to make the solutions presented available to as wide a range of students as possible. The TC’s mission is to ensure that the information presented is as widely available as possible, and it therefore organises many events to present Industry4.0 to the general public.


TC is currently presenting nearly 20 Industry4.0 solutions, some of which are working models of basic Industry4.0 technologies developed by university departments to solve industrial problems, and others are Industry4.0 solutions and products provided by our industrial partners, which have already been proven in practice and can even be purchased.


Open day: During the Open Day, anyone will have the opportunity to visit the Technology Centre. During the visit, visitors will be given a brief introduction to the concept and capabilities of Industry 4.0, as well as a complete tour of the Technology Centre, during which they will be able to see scenarios and Industry 4.0 solutions, briefly summarising their technical content and their place in Industry 4.0. Registrations for the open days can be made after prior announcement by email to ipar4@mail.bme.hu. The event is usually held on the first Friday of the month.

For students: Every semester, students at BME VIK have the opportunity to join the work in the TC in the framework of the Thematic Laboratory, Project Laboratory, Thesis or Diploma Project courses. Students can join IoT developments, either TC’s own projects or those of our corporate partners. Our topics include, for example, learning about the ThingWorx and MindSphere IoT platforms and solving an IoT development task.

For enterprises

The Industry 4.0 Model Factories flagship project offers a free programme that provides key practical experience and knowledge to productive micro, small and medium-sized enterprises to learn about Industry 4.0 technologies and their applicability, and thus increase their competitiveness.

Participants will receive a wide range of practical information and knowledge on the key topics of Industry 4.0, as well as practical help that, if applied properly, will help them increase their competitiveness: reduce operating costs, increase productivity and minimise passive production times. All this can help you to qualify as a supplier and enter new markets. A basic level of development is needed to apply the achievements of Industry 4.0, but the programme also helps to achieve this.

5G campus network


The private 5G test network launched on the BME campus in 2022 has been established in cooperation of BME FIEK, Nokia (supplying and operating the equipments), and Vodafone (providing the spectrum). A special feature of the network is that it is a standalone (SA) network, i.e. it is based on 5G innovations from the radio to the backbone, as opposed to the currently publicly available NSA (non-standalone) networks, which also use elements of existing 4G infrastructure and therefore do not support all 5G features. At the moment, our 5G campus network is the only research 5G network in the country that supports all 5G functionalities.

The network consists of 52 radio stations, providing some (although not full) indoor coverage in buildings V1, Q, I, Ch, Z and L of BME, including all FIEK labs. The backbone network connecting the buildings is implemented with optical links.


The 5G campus network is an open innovation platform, with access for businesses. Through individual research and development agreements it is possible to perform measurements, test industrial, practical use-cases and services. The network also includes an application server, on which a variety of customised, experimental network services can be deployed using virtual machines.

Participation in the education

The network is gradually being integrated into the education of the Faculty of Electrical Engineering and Informatics. As a first step, it provides infrastructure for project courses, lab measurements, thesis and dissertation work theses.
