One-line diagram (SLD) Simplified power system schematic showing major components —
generators, transformers, breakers — connected by a single line
representing all 3 phases. The top-level map of a power system.
Three-line diagram Expanded SLD showing all three phases separately. Used when phase-
specific connections (CTs, PTs, transformer windings) must be precisely
documented for protection design.
DC elementary diagram Detailed wiring schematic of DC control circuits in a substation — shows
how relay contacts, trip coils, and alarm circuits interconnect. The "nervous
