High-Voltage Drawing Studio

Are you studying Electrical Engineering or Sound Engineer? Are you sociable? Do you think learning at home is boring? Then drop by the High-Voltage Drawing Studio, or Hochspannungszeichensaal (HSZS for short), for an ideal all-inclusive revision room!

The HSZS is a community of students of Electrical Engineering and Electrical Engineering and Audio Engineering who run a joint revision room. Students have been bringing their courses to life together in the HSZS – right on the Inffeldgasse campus – since 1973, exchanging experience with colleagues and revising for exams in study groups. Of course, they celebrate their successes together too. In addition, the drawing studio is also intended to be a platform for discussion with professors, graduates, and representatives of industry and business.

No matter which exam you’re revising for, there’s always someone in the drawing studio you can team up with to prepare for and follow up exams. There seems to be no limit to the creativity in planning ventures or projects: from building a special tapping transformer for mobile beer tapping to a bicycle workshop.
