Electrical Substations Toolkit
iOS Universel / Education
This app is a comprehensive visual reference tool for electrical power engineers, designers, technicians, and students working with high-voltage substations.
This app features over 160 professional engineering illustrations of a 115/13.8 kV Ring Bus Power Substation — covering every major system from the transmission-level switchyard through the medium-voltage distribution equipment, control building, protection relays, SCADA systems, grounding, and civil/structural elements.
What's Inside
This app organizes its content into clearly defined categories so engineers can navigate directly to the system they need:
- Single-line and three-line diagrams
- Protection and relay wiring diagrams (including 87T differential, 50/51 overcurrent, 67 directional, and 50BF breaker failure)
- DC control and alarm wiring diagrams including battery ground fault detection
- SCADA and RTU wiring diagrams
- Civil, structural, and grounding drawings
- Equipment layouts and elevation drawings
- Aerial perspective illustrations showing equipment arrangement
New in Version 1.1
- Illustration Search — Find any of the 160+ drawings instantly by title across all categories
- Knowledge Quiz — 30 multiple-choice questions covering substation protection, equipment, standards, and design fundamentals, with explanations for every answer
- Personal Notes — Attach your own engineering notes to any illustration for quick field reference
- Favorites — Mark frequently used drawings and access them in one dedicated tab
