DC grids are an ideal solution to support the increased requirements of the onboard power (and in some cases energy storage) system. Proper protection however remains challenging. During this presentation we will present protection possibilities based on the solid-state DC breaker technology. Thanks to the ultra-fast switch-off times,(within microseconds) it prevents arching in case of short-circuit situations.
The following topics will also be presented:
– closed bus operation
– zone protection
– detection of single earth faults.
