Substation Tools

A calculation toolset based on IEC 60865 for estimating mechanical forces in AC conductors during short circuits, using practical worst-case methods and accounting for real-world stresses in design.

OverviewShort-circuitThermal

Short-circuit effects

Calculate how the conductor moves and how much force it experiences during and after a short circuit, including effects on sag and spacing, using temperature extremes and choosing the worst-case results for safe design.

Thermal bare conductors

Check whether a bare conductor or busbar can handle a short-circuit without overheating: enter fault currents and duration (or a multi-step fault sequence), together with cross-section and temperature limits, and see whether the resulting current density stays below the allowed value.
