Electrical Grid Design & Power Flow Simulation
ZeloGrid replaces legacy tools like ETAP and DIgSILENT with AI-native electrical grid design software. Draw professional IEC single-line diagrams, run power flow analysis, and collaborate — all from your browser.
Everything you need. Nothing you don't.
Built by electrical engineers, for electrical engineers. Our grid design tools provide everything you need in modern electrical design software.
IEC Single-Line Diagrams
Full IEC 60617 symbol library for professional single-line diagram software. Transformers, switches, earthing, loads, busbars — every symbol you need rendered precisely.
AI Network Builder
Type "Add a 35m feeder from bus R4 with three residential loads" and watch ZeloGrid draw it. Natural language to professional SLD.
Power Flow Simulation
Advanced power system simulation tools with Newton-Raphson load flow. Voltage profiles, line currents, losses — overlaid directly on your diagram. Results in seconds.
Browser-Native Canvas
No install. No licence server. Open a browser, start drawing. Works on desktop and iPad. Share a link with any colleague.
Professional Export
Export to SVG, PDF, or PNG. Diagrams that look exactly like they came from a professional drafting package. Client-ready output.
AI Report Generator
Simulation complete? Ask ZeloGrid to write the power flow report. Results, observations, recommendations — in plain English.
