A paper one‑line, and a switching order nobody can trace.

NodeFabric is a live circuit model for municipal utilities and electric cooperatives. Model the circuit once, then plan, validate, and execute switching against the same picture — from the office to the pole.

Feeder 1204 — One-LineFEEDER-1204 · 12.47 kV · Rev 4
The NodeFabric one-line for feeder 1204, animating a restoration: the sectionalizer is opened, 415 customers go dark, and the normally-open tie to the adjacent feeder is closed to pick them back up.

Illustrative feeder. Switching and energization state are simulated for demonstration — see real screenshots.

NodeFabric

One-line diagrams and switching

Turn your GIS connectivity model into an operational one-line. Trace feeders, simulate switching sequences, see energized and de-energized sections, and compare restoration paths before work begins in the field.

  • ModelMulti-feeder topology compiled from GIS or CSV exports, with tie points and normal open positions.
  • SwitchBuild an order step by step. Each step is validated against the current state before it is accepted.
  • TraceEnergization propagates from every source, so de-energized sections are visible immediately.
  • CountCustomers out per step, so you can compare two restoration paths on the same screen.
  • ShareClearances, hold tags, and revisions on one model, so the office and the crew read the same picture.
  • RecordEvery change carries a name and a timestamp, so the audit trail writes itself.

Web based. No CAD license required.

GridQL

Open-source query language for grid data

Ask your network model questions in the grid’s own terms — which customers are beyond this recloser, who is out right now — without knowing how the GIS or database behind it is laid out.

  • TraceUpstream, downstream, and protection zones, following the circuit as it is built.
  • EnergizeWho has power right now, traced through the switches as they currently stand.
  • ImportGIS CSV exports, Postgres, CIM, and OpenDSS, read through a mapping of your own column names.
  • ReuseSaved queries with parameters, so a report written once runs on any feeder.
