One-line diagrams with built-in analysis
Build your one-line diagram and get short circuit, load flow, and equipment sizing results — all from the same tool. No separate drawing and analysis software.
What you get
Place components, connect them, and the electrical model builds itself. No learning curve.
Short circuit, load flow, and equipment sizing run on the diagram. No separate analysis tool needed.
Standard equipment data built in. Select a device type and electrical properties populate automatically.
Export clean, presentation-ready one-line diagrams as PDF.
Components snap to nearby buses. Building the diagram is fast and frustration-free.
No software to install. Open a browser tab and start building.
One tool for diagram and analysis
Most engineers use one tool to draw the one-line and another to run studies. ekx combines both — your diagram IS your analysis model.
- Drag-and-drop components onto the canvas
- Connect devices and the electrical model builds automatically
- Short circuit and load flow results appear instantly
- Export the diagram and study results together
Start free. Upgrade when you need more.
Free tier includes 1 project with up to 2 buses. Paid plans start at $27/month for consultants and $149/month for unlimited access.
