DESCRIPTION:The transmission of a growing amount of renewable energy resour
 ces\, offshore wind in particular\, can be implemented effectively and eff
 iciently by multi-terminal HVDC transmission grids. Protection of these gr
 ids will require the interruption of DC fault currents. Traditional AC cir
 cuit breakers require current zero crossings to interrupt fault currents. 
 The absence of this periodic current zero in DC systems has led to the dev
 elopment of DC circuit breakers\, and entirely different approach towards 
 interrupting DC short-circuit currents. This presentation will explain the
  basic operating principles of HVDC circuit breakers and different ways of
  implementing them in HVDC grids. Based on that\, the testing challenges a
 long with a description of a sample test circuit capable of performing all
  relevant electrical stresses in a one-circuit one-shot test will be prese
 nted. Finally\, laboratory test results of three different types of HVDC c
 ircuit breakers will be presented and discussed. The presented information
  is a result of the work done in an EU-funded project (Progress On Meshed 
 Offshore HVDC Transmission Networks or PROMOTioN for short - www.promotion
 -offshore.net) and coordinated by DNV GL as a partner.\n\nSpeaker(s): Corn
