Metal-Oxide Arresters for HVDC Circuit Breakers | INMR effort is being put these days into planning meshed, multi-terminal HVDC networks. One of the crucial components in such grids is the circuit breaker, which must be capable of clearing DC faults without de-energizing the DC side of the grid. Several HVDC circuit breaker solutions have already been proposed with some realized into prototypes and others now in service.
