Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Adiabatic equation S=I√t/k using supplied coefficient; constant RMS fault current assumed. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits. Adiabatic equation is restricted to clearing durations up to5seconds with constant RMS fault current. Current-limiting device let-through energy and temperature-dependent regimes require separate analysis.
