Short circuit analysis that runs itself
Calculate three-phase and line-to-ground fault currents the moment you connect a device. Duty checks happen automatically — no separate run button, no waiting.
What you get
Momentary, interrupting, and symmetrical fault current values at every bus in your model.
Device ratings are compared against calculated fault duties instantly. Failures are flagged in real time.
Short-circuit calculations use PandaPower's IEC 60909 engine for facility distribution studies.
Representative commercial and industrial systems are checked against PandaPower expected-result fixtures.
Fault currents update as you edit the one-line. Change a transformer impedance and see the impact immediately.
Runs in any modern browser. No dongles, no license servers, no IT tickets.
Generate professional short circuit study reports with a single click.
How ekx streamlines short circuit studies
Traditional tools make you build the model, configure the study, wait for results, and then check duties manually. ekx collapses all of that into one step.
- Fault currents calculate live as you build the one-line diagram
- Device duty checks run automatically — no separate study configuration
- Results update instantly when you change any parameter
- Export a professional study report in one click

Three-phase, single line-to-ground, and line-to-line faults. Momentary, interrupting, and symmetrical (steady-state) values are calculated at every bus.
ekx uses IEC 60909-based short-circuit calculations through PandaPower. Automated tests compare representative commercial and industrial systems against checked-in PandaPower expected-result fixtures. Results still depend on the input data and should be reviewed by the engineer of record.
Yes. You can export a professional short circuit study report as a PDF on paid plans. The report includes fault current values, device duty checks, and system parameters.
ekx validates representative short-circuit calculation paths with automated regression tests against PandaPower expected-result fixtures. Results should be verified by a licensed professional engineer, as with any analysis tool.
