How to use a single‑line diagram template.
- 01Describe the switchgear voltage level and incoming supply
Example: '11kV metal-clad switchgear, double busbar arrangement, two incomers from separate transformers, bus coupler normally open, 8 outgoing feeders with VCBs and numerical overcurrent relays.'
- 02AI generates the busbar and breaker lineup
ChatDiagram draws the main busbars, incoming circuit breaker symbols (with earthing switch if required), bus coupler, and all outgoing feeders in the correct order.
- 03Add protection relays and instrumentation
Specify protection relay types by ANSI function number (e.g., 51N for earth fault, 87T for transformer differential). ChatDiagram adds relay symbols and CT/VT connections on the appropriate feeders.
- 04Show interlocking and bus coupler scheme
Describe the interlocking philosophy (key interlock, electrical interlock, or protection-based auto-transfer). ChatDiagram annotates the bus coupler with its normal state and auto-transfer conditions.
- 05Export for factory acceptance testing
Export the SLD as SVG or PNG for inclusion in the switchgear specification, factory acceptance test (FAT) procedures, and as-built documentation packages.
Questions about single‑line diagram templates
Can ChatDiagram draw a double-busbar MV switchgear SLD?
Yes. Describe the double busbar arrangement with bus coupler and busbar selector switches. ChatDiagram will draw both bus sections, the coupler, and the individual feeder connections with selector positions annotated.
Does it support motor control center (MCC) bucket layouts?
Yes. Describe the MCC incoming, bus plug arrangement, and individual motor starters (DOL, star-delta, VFD fed). ChatDiagram draws each bucket or module in the single-line representation.
How are protection relay ANSI numbers shown?
ChatDiagram annotates each relay symbol with its ANSI function number(s) (e.g., 51/51N, 27/59, 87). You can ask for a relay legend table to be included in the diagram.
Can the SLD show draw-out vs. fixed-mounted breakers?
Yes. Specify whether circuit breakers are draw-out (withdrawable) or fixed-mounted and ChatDiagram will use the appropriate symbol variant and add a test/service position note for draw-out types.
