Single line diagrams that actually calculate
Most SLD tools give you a drawing. ekx gives you a live electrical model. Place a transformer, connect it, and the system knows its impedance, ratings, and position in the network.
What you get
Place buses, transformers, cables, loads, and protection devices with intuitive drag-and-drop.
Your diagram isn't a picture — it's a model. Every connection carries electrical meaning.
Select from standard device specifications or enter your own. No manual data entry for common equipment.
Components snap to nearby buses automatically. No fiddling with connection points.
Export your SLD as a clean PDF ready for client deliverables or permit submittals.
Your work saves automatically. No more lost files from software crashes.
More than a drawing tool
Traditional SLD software separates the diagram from the analysis. In ekx, the diagram IS the model. Build once, get results immediately.
- Every component you place has real electrical properties
- Short circuit and load flow run on the diagram automatically
- Equipment sizes update live as you change the design
- Export professional one-line diagrams as PDF

No. The diagram is the electrical model. When you place a transformer and connect it, ekx knows its impedance, ratings, and where it sits in the system. Short circuit and load flow calculations run on the model automatically.
Buses, utility feeds, generators, transformers, cables, protection devices (breakers, fuses), motors, and static loads. Each has configurable electrical properties.
You can import device data via CSV/spreadsheet. The diagram itself is built in the ekx editor using drag-and-drop.
Yes. Export as PDF for client deliverables, permit packages, or internal documentation. DXF export for CAD integration is also available.
