Presets
System Parameters
BESS DC bus voltage. Range: 48V–1500V.
Maximum available fault current at the point of evaluation.
Internal resistance of battery pack — used for voltage sag model.
Time from fault detection to fault clearing. Typical: 0.2–1.0 s.
Distance from arc to worker. NFPA 70E default: 450 mm (18 in).
