Kema Labs variable frequency ultra-high current test laboratories can test any equipment that requires either a high current test or a special test frequency (or a combination of both). Tests can be done in triple phase or single phase. Our variable frequency and ultra-high AC current test laboratories can test at any desired test frequency between 15 Hz and 65 Hz with one single current source. We can test any large equipment with permanent current up to 50,000 A in our 960 m3 test bay.

Some examples of test equipment:

  • Generator bus duct systems
  • Generator switchgear
  • Large/HV gas insulated switchgear
  • Large LV/MV switchgear and controlgear assemblies
  • Gas insulated lines
  • Current transformers and instrument transformers for high current applications
  • HV/LV prefabricated substation
  • Prefabricated switchgear

Selected applicable standards:

  • IEC 62271 – High-voltage switchgear and controlgear
  • IEC 60076 – Power transformers
  • IEC 61439 – Low-voltage switchgear and controlgear assemblies
  • IEC 60947 – Low-voltage switchgear and controlgear
  • IEC 60353 – Line traps for AC power systems
  • IEC 61869 – Instrument transformers
