Live tools
Real planning tools, not just theory.
Interactive tools GRIDRA is building for real power systems planning work — grounded in engineering, and open to try right now.
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.
