Substation Engineer Suite vs Faraday

Substation Engineer Suite is the complete professional reference and learning suite for high-voltage power substation design — a fully interactive 3D substation, an extensive engineering drawing library, IEEE/NFPA references, and a full set of field calculators, all in one app. Whether you're a power engineer reviewing a single-line diagram, a student learning how a substation actually works, or a field technician who needs a fast calculation on site, SubstationEngineer puts substation knowledge in your pocket — and it works completely offline. The app is organized into two modules. Buy only what you need, or get both in a discounted bundle. ELECTRICAL SUBSTATION TOOLKIT • 160+ professional engineering illustrations across 10 categories • Pinch-to-zoom with smooth swipe navigation • Favorites and personal notes on any drawing • Full-text search across the entire library • 10 engineering calculators (transformer sizing, fault current, grounding, and more) • IEEE / NFPA reference library • 30-question knowledge quiz 3D EXPLORER • Interactive 3D substation model with 54 tappable components • Tap any component for its code reference and engineering notes • X-Ray and Energize visualization modes • 8 filterable equipment systems • 15 engineering calculators (IEEE 80 grounding, fault, transformer, and more) • Learning Hub: quiz, glossary, guided tour, and fault simulator • Substation image gallery WHY YOU'LL USE IT • Works 100% offline — no account and no internet connection required • One-time purchases — no subscriptions, ever • Buy a single module or unlock everything with the bundle • Grounded in IEEE and NFPA engineering standards • Built for real engineering work, from the classroom to the control house From study to substation, SubstationEngineer is the reference you'll actually keep on your phone.
