Feeder Distribution Single Line Diagrams

Feeder distribution single line diagrams represent the electrical path from a main switchboard or substation bus through feeder cables, sectionalizing switches, and protective devices to each load group or downstream transformer.

How to

How to use a single‑line diagram template.

  1. 01Describe the source bus and feeder arrangement

    Example: '11kV incoming via ring main unit, three outgoing feeders to distribution transformers at 400V, each with HRC fuses and metering. Feeder 2 is a ring return.' Specify voltage level and protection philosophy.

  2. 02AI draws the bus and feeder structure

    ChatDiagram places the main bus, incoming supply symbol, and outgoing feeder branches with circuit breakers or fuse switches at each connection point.

  3. 03Add protection and metering devices

    Specify protection relay types (ANSI 51, 67, 27/59) and metering requirements. ChatDiagram adds current and voltage transformer symbols, relay boxes, and energy meter symbols on each feeder.

  4. 04Show bus tie and transfer switching

    Describe any normally-open bus tie breakers or automatic transfer switch arrangements. ChatDiagram adds these to the SLD with their normal operating state annotated.

  5. 05Export for protection coordination studies

    Export as SVG or high-resolution PNG to use as the basis for your protection coordination study or include in a design package for client review.

FAQ

Questions about single‑line diagram templates

Can ChatDiagram draw an MV ring main unit (RMU) in the SLD?

Yes. Describe the RMU with incoming and outgoing cable feeders and the fuse-switch or VCB positions. ChatDiagram will draw the RMU block with load break switches and the ring continuity shown.

Does it support IEC and ANSI symbol standards?

The Schematex SLD renderer uses internationally recognized single-line symbols. Ask for ANSI or IEC style in your prompt and ChatDiagram will use the appropriate symbol set.

How do I show cable sizes and conductor ratings on the SLD?

Mention conductor sizes and types in your prompt (e.g., '3-core 185mm² XLPE 11kV cable'). ChatDiagram annotates each feeder line with cable type, size, and ampacity.

Can it generate a load schedule alongside the SLD?

You can ask ChatDiagram to include a load summary table as part of the diagram, showing connected load (kVA), demand factor, and maximum demand for each feeder.
