Fault currents at every bus
Not a single-point calculator. ekx calculates fault currents at every bus in your system in one run, and marks them stale when you change the model.
What you get
Three-phase fault currents calculated at every bus in your model.
Initial symmetrical (Ik'') and peak (ip) fault current for device evaluation.
Fault currents use PandaPower's IEC 60909 calculation, from a pre-fault voltage you choose.
Automatic comparison of fault currents against device interrupting ratings.
See how fault currents propagate through your entire system, not just at one point.
Add a source or change an impedance, then run short circuit again to update every bus.
Fault current analysis built into the model
Standalone calculators give you one bus at a time. ekx gives you every bus in the system in one run, with automatic device duty checks.
- Fault currents appear at every bus the moment you have a source
- Device duty checks run automatically against calculated values
- Change any impedance and run again to see the system-wide impact
- Export results in a professional study report format

No. ekx calculates fault currents at every bus in your system simultaneously. It's a full short circuit study, not a single-point calculation.
Three-phase fault current at each bus: initial symmetrical (Ik'') and peak (ip) values. Line-to-ground faults are not available yet.
Yes. Calculated fault currents are automatically compared against device interrupting ratings. Devices that are underrated are flagged.
IEC 60909, through PandaPower. The pre-fault voltage is either a fixed percent of nominal (100% by default) or the IEC voltage factor of 1.10.
Calculate fault currents across your entire system.
Every bus, every source. Automatic duty checks included.
