Powering the Future: HVDC Technology for Sustainable Energy
Our cutting-edge testing facilities support the increasing demand for High Voltage Direct Current (HVDC) technology, essential for the efficient transmission of bulk power over long distances and the integration of renewable energy sources into modern power grids.
Type Testing and Certification
We specialize in detailed type testing and certification for HVDC cables and cable accessories, strictly adhering to international standards and client-specific specifications, including IEC 62895 and CIGRE TB 852. Our services ensure that HVDC cable systems are not only efficient but also reliable for long-distance power transmission.
Our testing program includes both electrical and non-electrical type tests. We conduct electrical type tests on complete cable systems and detailed assessments of individual components and cables. A key element of the electrical testing is the heating cycle voltage test, which evaluate cable system performance under specific electrical and thermal conditions. Additionally, our HVDC cable testing laboratories addresses unique requirements, including maintaining a specified temperature difference across the cable insulation and performing serial superimposed impulse voltage tests on the system with the highest efficiency.
Prequalification Testing
In addition to type testing, KEMA Labs offers prequalification testing of HVDC power cable systems in accordance with IEC 62895 and CIGRE TB 852. This testing process validates the lifetime and reliability of HVDC power cable systems, ensuring technical resiliency of the solution for at least 40 years, with a strong testing program executed in 1 year, confirming the readiness of power cable systems for integration into modern. electrical networks.
TOV Testing
The growing integration of extruded HVDC cables into the energy transmission system raises new questions regarding transient failure voltage waveforms and their simulation in the laboratory.
In this respect, immediately from the first simulations performed by the TSOs in 2018, it was found that the IEC and CIGRE standard requirements were not sufficient to cover cases of dangerous transient waveforms in growing DC networks. Some TSOs, engaged in the transport of electricity from offshore wind farms in the North Sea and the Baltic Sea decided to verify the greater ability to withstand electrical transients of 525kV DC cable systems, which occur in HVDC Schemes such as during pole to ground fault, pole to pole fault, AC side faults, etc.
KEMA Labs, has been the first independent laboratory to perform this unique type of test and is fully capable to support all the worldwide customers in it Lab
