Circuit breakers, despite any techy magic happening beneath the surface, should be the most predictable things in the world.

Abstract: Solid-state circuit breakers (SSCBs) are critical components in the protection of medium-voltage DC distribution networks to facilitate arc-free, fast and reliable isolation of DC faults.

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 ...
