Produce a switchgear register from single-line diagrams.
Electrical handover on any process or power facility includes a master switchgear register. Every breaker, transformer, motor, generator, and protection relay with rating, position, and ANSI/IEEE C37.2 device numbers. The single-line diagrams carry it all. The spreadsheet trail does the typing.
Workflow.
- 01
Upload the SLD set
Single-page or multi-page SLDs, including legacy scanned drawings. Pages route to the electrical extractor on first pass.
- 02
Section grouping
Bus bars, switchgear sections, and feeder relationships are extracted with their hierarchical structure preserved. Each breaker carries its associated protection relay device numbers, 52 main breaker, 87 differential, 50, 51 overcurrent, 27, 59 voltage.
- 03
Export the register
Excel workbook grouped by section, with protection-device columns alongside the breaker tag. CSV for asset-management imports. JSON for digital twin or DCS handover ingestion.
What you get.
- Switchgear register grouped by section and bus, with rating and current per breaker
- Protection-device list with ANSI/IEEE C37.2 device function numbers per breaker
- Transformer schedule with rating, taps, vector groups, and cooling class
- Motor and generator schedule with rated power and starting class
FAQ.
01Are ANSI/IEEE C37.2 device function numbers, 52, 87, 50, 51 extracted as their own field.
Yes. SLD reading covers the C37.2 numbering scheme so device functions are tagged distinctly from the breaker tag. Each breaker carries its protection relay set as a structured array on the output.02Can the register feed an asset-management import like Maximo or SAP PM.
Yes. The JSON export carries per-asset metadata in the structure most asset-management systems expect. Integration teams map the JSON exports to Maximo, SAP PM, and Infor EAM data models using each system's own import path.
