High Voltage Laboratory


The High Voltage Laboratory has state-of-the-art equipment that can be used in the testing of materials and the study of different HV phenomena. The high number of MWB HV modules allows designing high-level detailed setups that can be used for experiments with fundamental HV theories. This is essential for students as HV engineering in nature is an experimentally based science.

The HV laboratory also has an 800kV impulse generator for testing with both lightning and switching impulses.

Special equipment

Below please find a list of some of the existing equipment:

  • 800kV Impulse generator with voltage divider
  • 2 sets of 100kV Lightning impulse setup (can be used for universal purposes)
  • 200kV AC Cascaded transformers
  • Digital partial discharge detector
  • Capacitance and loss angle measuring bridge
  • Modules (capacitors, resistors, spark gaps, rectifiers, pressure vessels etc..) that can be used in the designing of different test setups
  • Dielectric frequency response analyzer

Features & Services

The High Voltage Laboratory can be used for high voltage testing of all types of electrical insulation systems, ranging from insulators on air lines, wind turbine wings, solid and liquid insulation materials, all the way down to printed circuit boards. In the laboratory there is a particular focus on research in insulation design as well as on the life of future power electronics devices for voltages over 1000 V; eg. converters to offshore wind turbines.
