KEMA Laboratories of DNV GL Energy, located in the west part of Arnhem, the Netherlands has more than 85 years of experience in testing, inspection and certification. At this location, test facilities have been tailor made for allowing HVAC components to be tested with many given setups, using a Plug and Play method. This offers KEMA Laboratories a flexible way of working and the ability to configure to HVAC components.
In addition to our HVAC capabilities, investments leading to the extension of our High-Power Laboratory, cleared the way for exploring HVDC opportunities, resulting in the commissioning of a new HVDC test facility. Located in the east part of Arnhem, at the industrial park Kleefse Waard (IPKW) situated along the river Rhine, it is not far from our KEMA Laboratories headquarters. Here we have once again implemented our uniform philosophy; parallel testing facilities, tailor made for Plug and Play, but now for HVDC components also. HVDC cable systems and submarine cables up to 320 kV, research and development for switchgear, etc., can all be catered to. This new location gives access to transportation by road and boat, making it easy to allocate HV components by water from multiple locations.
In short, a 600 kV DC-source forms the heart of our HVDC laboratory, followed by a transportable impulse voltage generator for super-imposed lightning and switching impulse tests. In addition, our own design unit for testing buried joints in water is available at our new location, making logistics for a joint less critical after extended testing. Currently most tests are carried out in accordance with CIGRE brochures or customer specifications as there are no international standards available. As part of our commitment to delivering trustworthy worldwide services, we are invested in HVDC research and development in cooperation with the Delft University of Technology, DNV GL Energy Advisory and KEMA Laboratories. We aim to enhance the reproducibility of testing and contribute to the development of a future IEC standard for HVDC cable testing.
