Research on Vacuum Switching

With an experience of over 50 years in vacuum switching, High Power Research Laboratory specialized in high power switching vacuum arc has modern facilities with adequate performance. The laboratory is equipped with test facilities for investigation of nominal, overload or short circuit regimes that may occur in vacuum switching.

The existing material basis allows to analyze with great accuracy the evaluation of the quality parameters of the vacuum interrupters (Vis) for example post-arc current and chopping current.


  • Maximum Power Test station for direct short-circuit current 50MVA
  • Modern command, control and protection systems
  • Modern measurement and data acquisition systems
  • Custom software developed "in house" for waveform analysis
  • Connections between the test and control devices is achieved through optical fiber
  • High speed camera for study of transient phenomena


  • High performance research in vacuum switching
  • Tests for certification of products
  • Tests for the development of modern vacuum switches
  • Electrical and mechanical endurance tests
  • Case studies specialization
