In the history of the High Voltage Laboratory, the first major piece of equipment put into use was the 250 kV transformer, which remains in use to this day, followed by the acquisition of an impulse voltage generator capable of producing a peak value of 1 MV. High-voltage live-line working appeared in Hungary in the 1970s, and at the same time the Laboratory was enriched with a 600 kV test transformer and a second, 750 kV impulse voltage generator. In the summer of 2012, the Laboratory underwent a complete renovation with industrial support, after which Hungary's largest Tesla coil was added to the row of main equipment.

The main venue of the work of the BME VET High Voltage Technology and Equipment Group is the High Voltage Laboratory belonging to building V1 of the Budapest University of Technology and Economics.
