In cooperation with other laboratories of  KONČAR – Electrical Engineering Institute laboratories, we offer environmental testing of various power electronics stated equipment using the available test facilities as test beds. Some of examples:

  • noise level testing of main traction converter for electric multiple unit train
  • temperature testing of railway level crossing half-barriers
  • temperature testing of main traction converter for diesel-electric multiple unit train
  • temperature testing of transformer control cubicle for nuclear power plant
  • EMC testing of static converters
  • IP testing of static converters.
