Learn

Everything for learning NumaSim — both how the tool works and the engineering behind it — in one place.

• NumaSim Simulator — a guide to the app itself: observables, power flow, subsystems, multi-rate monitoring, wire routing, the scope panel, and the chat / AI assistant. Start here to learn the tool.
• Courses (below) — structured, university-style courses that teach power-system engineering by building and running the models yourself. Each course is split into modules and chapters, every concept is paired with a circuit you open and run in NumaSim, and every chapter ends with problems and worked solutions. Start here to learn the subject, using NumaSim as your lab bench.

Who the courses are for

Practicing electrical engineers, graduate students, and advanced undergraduates who already know circuit theory and basic AC power, and who want to go deeper into how power systems are modeled and simulated. Each course states its own prerequisites on its syllabus page.

How a course works

• Read the theory. Each chapter derives the ideas from first principles — no black boxes.
• Run the lab. Worked examples come with an Open in app link that loads a ready-to-run circuit. You change a value, re-run, and watch the result move.
• Do the problems. Every chapter ends with problems. Solutions are tucked behind a toggle so you can check your work after trying.

Open in app is free

Opening and running any course circuit is free for everyone — no account needed. Editing or building your own needs a free account (up to the free size cap). See Plans & limits.

Available courses

• EMT Simulation of Power Systems — how electromagnetic-transient simulators represent a network, discretize its components, and march the full voltage/current waveform forward in time. Built around hands-on NumaSim circuits, from a first RL step response up through transmission lines, machines, and controls.

More courses coming

Future courses in development include power-system protection (instrument transformers, relay elements, coordination) and power-electronics control. Want one prioritized? Let us know through the in-app chat.
