Power Systems
Analysis
Reimagined
Arc flash studies, short circuit calculations, and TCC coordination in one unified platform. Drag. Drop. Analyze.
Validated against industry standards
Everything you need for power systems analysis
Industry-standard calculations, validated against 144,000+ test cases. From arc flash to coordination, all in one platform.
Arc Flash Analysis
Complete 13-coefficient model with automatic PPE categorization, arc flash boundary, and incident energy. Includes DC arc flash for battery systems.
Short Circuit Studies
Dual-standard support: IEC 60909 for international projects, ANSI C37.010/C37.13 per IEEE 551 (Violet Book) for North American systems.
TCC Coordination
800+ curves plus 5 smart families (MicroLogic, SEPAM) with equation-driven settings. Drag curves directly on the graph to adjust protection.
System Builder
Drag-and-drop electrical system design with in-place fault currents and arc flash results displayed directly on the diagram.
Auto-Coordination
Automatic protective device coordination per IEEE 242. Calculates optimal Ir, tr, Isd settings maintaining CTI margins while accounting for motor LRC and transformer inrush.
Reports & Export
Generate PDF arc flash labels, Word reports with methodology, and Excel exports. PE signature workflow for professional engineers.
Standards-compliant calculations
Every formula validated against industry reference implementations. Results you can trust for critical safety decisions.
