Technical data
Calculation basisIEC 60909-0
Fault typesThree-phase, line-to-line, line-to-earth
ResultsInitial symmetrical Ik", peak ip, breaking Ib, thermal Ith
NetworkGrid, generators, transformers, cables, busduct, motors
ExportBus-wise fault table in PDF and Excel
PlatformWindows 10 and 11
What you get
- Network drawn as a single-line diagram, not typed as a table
- Motor contribution included where the standard requires it
- Breaker breaking capacity checked against the fault at its bus
- Busbar and cable withstand passed back to Calc-Ax Cable
- Report lists every impedance used, so the result can be checked by hand
