Power Substation 3D Simulator puts an entire high-voltage substation in your hands. Explore the switchyard and control building in interactive 3D, make the structures transparent, and tap any component to learn exactly what it does. Built for electrical engineering students, apprentices, technicians, operators and inspectors, this app turns a complex substation into something you can see, rotate, filter and truly understand. EXPLORE IN 3D Rotate, zoom and orbit a complete substation: lattice transmission towers and incoming lines, power transformers, circuit breakers, disconnect switches, busbars, capacitor banks, reactors, the control building, grounding grid and more. Turn on X-Ray mode to make structures transparent so every electrical, protection and control system is visible at once. Energize the model to watch power flow along the bus and feeders. TAP TO LEARN: 49 COMPONENTS Tap any component for a full reference card covering its operating function, voltage level and classification, IEEE / IEC / NFPA / NERC code references, maintenance and testing intervals, common failure modes, safety precautions and operator notes. FILTER EVERY SYSTEM Use the side panel to show or hide eight equipment categories, or drill in and toggle individual components on and off while the 3D view updates live. Categories include Primary Equipment, Protection Relays, Control Systems, Auxiliary Power, Grounding and Safety, Communications, Transmission Feeders and Monitoring Systems. ENGINEERING TOOLS AN Engineering Tools tab with a full set of substation design calculators. 15 substation design calculators, grouped into five sections. Each calculator has slider inputs, the governing formula, a live result with engineering interpretation, and the relevant standard. LEARNING HUB Six built-in study modules: - Quiz: 28 exam-style questions on operations, relay protection, switching and electrical safety - Glossary: 46 substation terms explained in plain language - Guided Tour: follow power flow through the substation stage by stage - Fault Simulator: step through 7 fault scenarios and the protection response - Load Calculator: 5 tools for transformer loading, feeder capacity, voltage drop, short-circuit current and battery backup - Violations: 12 common design and installation issues with the correct practice REFERENCE LIBRARY A single-line diagram, a searchable equipment schedule, and an ANSI / IEEE C37.2 protective device-number and grounding quick reference. ILLUSTRATION GALLERY A built-in gallery of substation illustrations with smooth pinch and double-tap zoom. WHO IT IS FOR - Electrical engineering students and instructors - Apprentice and journeyman electricians and linemen - Substation operators and technicians - Protection and control engineers - Inspectors and anyone preparing for licensing or certification exams DESIGNED FOR IPHONE AND IPAD A universal app that supports portrait and landscape on every screen size.
