HVDC circuit breakers are believed to play an important role in realizing high availability and low losses in multi-terminal HVDC grids. Several technology concepts have been developed by manufacturers, but thus far no HVDC circuit breakers have been installed in Europe and hence operational experience is limited.
In order to increase the technology readiness level, improve confidence in the maturity of the technology and show that it is in principle ready for real-world application, PROMOTioN will demonstrate the most critical requirement: the DC fault current interruption performance. To this end, performance verification tests will be demonstrated on a three-module SCiBreak VARC HVDC circuit breaker prototype in the accredited independent KEMA high-power test laboratory, Arnhem, the Netherlands.
