Core Analysis

Short circuit analysis that takes one click

Calculate three-phase fault currents at every bus with one click. Duty checks against device ratings happen automatically.

What you get

Three-phase faults

Initial symmetrical and peak fault current at every bus in your model.

Automatic duty checks

Each run compares device ratings against the calculated fault duties and flags any that fall short.

IEC 60909-based method

Short-circuit calculations use PandaPower's IEC 60909 engine for facility distribution studies.

Regression-tested results

Representative commercial and industrial systems are checked against PandaPower expected-result fixtures.

Stale results are marked

Edit the one-line and the fault currents are marked stale. One click on Short Circuit brings them up to date.

No software to install

Runs in any modern browser. No dongles, no license servers, no IT tickets.

Export-ready reports

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 at every bus from one click on the one-line you drew
  • Device duty checks run automatically — no separate study configuration
  • After an edit, results are marked stale until you run short circuit again
  • Export a professional study report in one click

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/user/month for unlimited access.

Frequently asked questions

What fault types does ekx support?

Three-phase faults at maximum fault current. Initial symmetrical (Ik'') and peak (ip) currents are calculated at every bus. Line-to-ground and line-to-line faults are not available yet.

Which standards does the short circuit calculation follow?

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.

Can I export short circuit results?

Yes. You can export a short circuit study report as a Word document, an HTML page or a Markdown file on paid plans. The report includes fault current values, device duty checks, and system parameters.

How accurate are the results?

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.
