Power Systems
Analysis
Reimagined
Arc flash studies, short circuit calculations, and TCC coordination in one unified platform. Drag. Drop. Analyze.
Access is subject to product review and availability
Review-required evidence — independent review pending
A shared workspace for power systems analysis
Review-required beta with selected reference checks. From arc flash to coordination, all in one platform.
Arc Flash Analysis
IEEE 1584-2018 AC calculation path with incident energy and arc flash boundary for supported inputs. Assisted DC estimates require separate engineering assessment.
Short Circuit Studies
IEC 60909 studies with selected cross-checks and ANSI duty calculations for supported models. Confirm topology, fault type, and method limits before use.
TCC Coordination
Browse curve profiles and equation-driven settings. Exact-model provenance and settings matter: catalog presence is not engineering approval.
System Builder
Drag-and-drop electrical system design with in-place fault currents and arc flash results displayed directly on the diagram.
Auto-Coordination
Explore proposed protective-device settings and CTI margins for supported profiles. Independent review, manufacturer selectivity data, and project-specific motor/inrush checks remain required.
Reports & Export
Prepare study reports, data exports, and review-gated arc flash labels. Workflow approval records do not constitute independent validation or PE signoff.
Standards-based calculations
Selected reference checks support a bounded engineering review workflow. Independent project validation remains pending; review inputs, device evidence, and method limits before safety decisions.

IEEE 1584-2018 Full / reduced-current energy comparison Boundary at the specified energy threshold Iarc = f(Ibf, Voc, G, config) Short Circuit (IEC)
IEC 60909-0:2016 I"k = c × Un / (√3 × |Zk|) ip = κ × √2 × I"k Motor contribution depends on the network model Short Circuit (ANSI)
C37.010 / IEEE 551 Imom = Isym × MF (first-cycle) Iint = Isym × NACD × MF Closing duty depends on method and X/R Protection
IEEE C37.112 / IEC 60255 CTI = t_backup - t_primary; project-specific margin t = TDS × k / [(I/Ip)^n - 1] I²t = ∫₀ᵗ i²(t) dt Selected IEEE Checks
13 selected kernel cases at ±0.1%; two official-tool transcriptions still need retained case worksheets
Selected IEC Cross-Checks
Selected IEC 60909 cases compared with pandapower; coverage and tolerances are case-specific
Independent Review
Complete Annex D and ETAP/SKM project comparisons remain pending; no independent engineer approval is claimed
