Medium Voltage Laboratory

Introduction

The Medium-Voltage Laboratory was built in 2014 and it has state-of-the-art facilities unique in Denmark, which allow the testing of equipment up to 20kV/2MVA in a safe and controlled environment. Among others it is possible to test power converters, circuit breakers, transformers or insulations.

The main use of the new MV laboratory will be for testing the power electronic converters for future, large wind turbines having internally rated voltage above 1 kV.


Facilities

  • 20kV utility grid connection
  • A dedicated operator’s room and test room of 100m2
  • Prepared for air- and water-cooled equipment (cooling capacity 200 kW)
  • Up to 5 testing-bays
  • 20/20-10-6-3 kV 2 MVA test transformer
  • 20/0,69-0,4 kV 800 kVA test transformer

Features & Services

The MV lab can be used for load testing of power electronics converters and devices under fully-safe conditions. The MV lab is very suitable for prototyping and testing of new converters in the medium voltage range, for example for future offshore wind turbines. The tests can be followed both visually and via measuring equipment that is optically separated from the test room.
