Yard layout

Yard layout

The yard plan and sections are drawn at design dimensions from the single-line diagram: bays, equipment, roads, fence and buildings, with the clearances checked per the standards set.

Capabilities

Plan, sections and output

The layout sets the geometry that the earth mat, the lightning protection and the 3D model use. The sheet and the compliance checklist check the clearances of the standards set.

Layout
  • Yard layout plan and sections at the scales below
  • Air-insulated (AIS) or gas-insulated (GIS) switchgear per HV yard
  • GIS in an indoor hall with SF6/air bushings
  • Bays, transformers, roads, fence and buildings
Output
  • Clearance checks shown on the sheet
  • Title block and revision table
  • Output in DXF and PDF
  • DXF import into the sheets for existing drawings
  • Selection linked to the SLD, the 3D model and the BOM
Layout edits
  • Equipment moved along its bay, transformers and reactors, buildings moved and turned in 90° steps
  • MV and reactive power areas, burnt-oil pit, road widths and positions, fence sides
  • On the yard plan or in the 3D model, within the constraints of the object
  • Clearance checks on the moved objects in the design run
  • The sheet, sections, 3D model, earth mat and BOM follow the edited layout

Layout edits

Screens of the yard plan and the 3D model in Edit layout, in the design workspace.

Edit layout on the yard planSelect an object and drag it, or type its offset. A moved object shows at its new place until Run design, and the list holds the edits.

Edit layout in the 3D modelIn Plan, a drag on an object moves it on the ground within its constraints. The same object is selected on the yard sheet.
