Electrical system design with analysis built in
Design tools draw pictures. Analysis tools run numbers. ekx does both at once. Draw the one-line diagram and get short circuit, load flow, and equipment sizing results as you design.
What you get
The one-line diagram IS the analysis model. Build once, get results immediately.
Cables, breakers, and transformers size per NEC as you connect them.
Short circuit analysis runs on the model continuously. No separate study step.
Load flow shows bus voltages and voltage drop as you add loads and cables.
Export one-line diagrams and study reports for client deliverables.
Change any parameter and see the system-wide impact instantly. Design iteratively.
Design and analysis in one workflow
Traditional electrical design means: draw the one-line, manually enter data into analysis software, run studies, go back and update the drawing. ekx eliminates the back-and-forth.
- Draw the one-line — analysis runs on the diagram automatically
- Equipment sizes as you connect — no separate sizing step
- Fault currents and voltages visible as you design
- Change the design, see updated results instantly

No. ekx combines the one-line diagram (design) with short circuit, load flow, and equipment sizing (analysis) in a single tool.
Yes. ekx uses ANSI/IEC methods for short circuit, Newton-Raphson for load flow, and NEC 2023 for equipment sizing. Results are suitable for professional engineering work.
Yes. Export one-line diagrams as PDF, generate study reports, and create professional documentation for client deliverables.
