Trials of a direct current (DC) circuit-breaker module prototype – a technology key to the development of a high-voltage DC meshed offshore grid off Europe – have been successfully completed at DNV GL’s laboratories in Arnhem, the Netherlands.
The testing, carried out by SCiBreak as part of the €52m ($60m) EU-backed PROMOTioN ( Progress on Meshed HVDC Offshore Transmission Networks) scheme, saw a fault current created by low-frequency short circuit generators interrupted against a transient interruption voltage exceeding 40kV, “verifying the functioning of a novel technology concept and constituting a major milestone for the project”.
