Introduction to wiring diagrams
As already written earlier regarding LV switchboard, wiring diagrams are used to show control and signalization principle of operation inside switchboard. Usually they are given in form of electrical circuits between two lines which are representing control voltage potentials.
Of course, various types of signals can be transferred outside switchboard, for the purpose of measuring, monitoring, or control, i.e. to be used for SCADA applications.
Within this article, we will be talking about wiring diagrams inside medium voltage (MV) switchgear. Basically, same rules and principles apply here as well.
