Medium voltage load break switch testing

mv load break switch testing

DNV GL provides world-renowned testing and certification of MV load break switches according to standards such as IEC 62271-103, IEEE 1247 and IEEE C37.74

DNV GL’s world-renowned testing and certification provide independent proof that your medium voltage load break switches meet all the necessary requirements, opening doors to let you export components across the globe.

We test and certify medium voltage load break switches against recognised international standards such as IEC 62271-103 and IEEE 1247. Our efficient test methodology helps to reduce testing costs, while our facilities in the Netherlands, USA and Czech Republic accurately simulate the operating and fault conditions components face in the field including high short circuit powers. In addition, we can act as an independent witness for on-site tests.

Range of tests

  • Short circuit tests
  • Dielectric tests
  • Temperature rise tests
  • Mechanical tests

Test can be performed at 50 or 60 Hz.

Internationally recognised certification
Depending on the range of tests chosen, a successful load break switch will receive a KEMA Type Test Certificate. This internationally accepted Certificate is evidence that your component meets all the requirements of the defined standard or specification. The range of KEMA Type Test Certificates for medium voltage load break switches includes:

  • KEMA Type Test Certificate of Complete Type Tests
  • KEMA Type Test Certificate of Switching and Short-Circuit Performance
  • KEMA Type Test Certificate of Dielectric Performance
  • KEMA Type Test Certificate of Temperature-rise Performance

Alternatively, you can choose to receive a Report of Performance or an Inspection Report. These reports describe the tests conducted, but do not provide evidence that a component meets a certain standard or specification.
