The present invention relates to a medium or high voltage power distribution cubicle with integrated digital communication busses. More particularly, the present invention relates to a medium voltage power distribution cubicle which is suitable for the use in indoor switchgear systems for electric power distribution. The power distribution cubicle according to the invention comprises one or more primary equipment devices aimed for performing one or more primary functions (e.g. breaking, conducting the nominal current, withstanding the short circuit current, disconnecting, earthing, isolating live part from operators) and one or more secondary equipment devices aimed at performing secondary function (e.g. protection, interlock, supervision, control, measure, metering). According to the invention at least a first intelligent electronic device is operatively communicating with said one or more secondary equipment device by a digital communication bus which is coupled to an associated first digital connector. |
