Abstract: The ultrafast protection speed requirement motivates the adoption of solid-state circuit breakers (SSCBs) for dc shipboard power systems. A 1 kV and 1.5 kA SS dc circuit breaker (DCCB) based ...
Abstract: The inclusion of a large number of controllable semiconductor devices in conventional hybrid dc circuit breakers (HCBs) may significantly increase the cost of an HVdc grid protection scheme.
This article is the first in a series of articles that will help to bring light to the maintenance practices presently applied to power circuit breakers. A list of the most popular tests used; with ...
