Engineer the grid, right in your browser.
Simulation, planning and learning tools for power systems, smart grids and high voltage engineering — for students, engineers and consultants alike.
Live tools
Real engineering, right in your browser.
No installation, no account, no waiting — plan EV charging capacity, analyze a real load profile, and simulate fleet charging risk in minutes.
EV Charging Capacity Planner
Check whether a building's grid connection can support a planned EV charging installation — with and without dynamic load management.
Load Profile Analyzer
Upload a load profile CSV and get peak demand, load duration curve, daily/weekly shape and a data quality check — automatically.
EV Charging Load Simulator
Monte Carlo simulation of a real EV fleet combined with your site's load — P50/P90/P95/P99 peak demand, overload probability, and a safe fleet size.
Fault Analysis Lab
Symmetrical-components short-circuit analysis for a source-transformer-cable feeder — pick a fault type and location, then see the resulting three-phase waveforms and phasors before and after the fault.
Transformer & Magnetic Circuit Designer
Design the winding turns and core for a transformer or inductor from classical magnetic-circuit theory — set the voltage, frequency and core, add an air gap or a flux concentrator, and see the required turns, saturation margin and flux split.
How it works
Learn it, simulate it, ship it.
Learn
Structured lessons across power systems, smart grids, renewables, high voltage and grid economics.
Simulate
Run real engineering tools — EV charging capacity, load profiles, fleet simulations — directly in your browser.
Analyze
See peak demand, overload risk and data quality clearly, with every assumption shown, not hidden.
Design
Turn results into a decision — a safe fleet size, a capacity upgrade, a load management strategy.
Focus areas
Deep in the topics that matter.
Power Systems
Generation, transmission and distribution fundamentals.
Smart Grids
Digitalization, automation and intelligent grid control.
High Voltage Engineering
Insulation, protection and high voltage equipment.
Renewable Energy
Integrating wind, solar and storage into the grid.
Grid Stability
Stability, resilience and power quality challenges.
AI & Digitalization
Data-driven and AI-assisted grid analysis.
For students
Learn the theory, then use the tools engineers use.
43 lessons across six tracks, plus the same EV charging, load profile and simulation tools built around real engineering problems — something to show, not just notes.
