The KEMA High-Voltage Laboratory is a well-known independent laboratory for testing and certification of medium and high voltage components used in the electrical infrastructure. Our customers are manufacturers and utilities world-wide, in particular Europe, Asia, America and the Middle East. 

The KEMA High-Voltage Laboratory issues Type Test Certificates and Test Reports for tests on cables, cable accessories, insulators, power transformers, instrument transformers, GIS, switchgear, panels and other components. We have several flexible test bays available and can work for clients in parallel.

For on-site testing we operate several transportable test facilities for commissioning and maintenance, tests on medium and high voltage cables and overhead lines, complete substations, power transformers and generators. For example: a series resonant voltage source for commissioning tests of cables up to 250 kV/80 A with partial discharge measurements. And 0,1 Hz test vans to detect weak spots in medium voltage cable systems.

The KEMA High-Voltage laboratory is accredited according to IEC 17025 and is a member of STL, IEC and CIGRE. Our measuring systems are of high accuracy and we are accredited by the Dutch Accreditation Council for calibration of measuring systems.

Our test engineers and technicians are highly qualified and experienced in (type) testing of medium and high voltage components. We provide very efficient and cost effective testing of your components. Maximum flexibility is offered for meeting your requirements.
