Substation Engineer Suite
3D Models, Drawings & Toolkit
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
A fully interactive 3D substation, 160+ engineering drawings, IEEE/NFPA references, and 25+ calculators — the complete substation reference, 100% offline.
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.
