Short circuit protective device
SpletA protective device study analyzes the impacts of short circuits and equipment failures within a facility and determines the effects on the facility operation. It is study that must be combined with arc flash hazard analyses required by present electrical safety codes and enforcement agencies. Splet09. dec. 2024 · Solid state power controller (SSPC) has been widely used in spacecraft. At present, its power distribution and protection mostly adopt the "SSPC + fuse" mode. In order to prevent the SSPC from acting first when the downstream load is short-circuited, resulting in the power failure of the entire channel, accurate SSPC protection characteristics must …
