Engineering Disciplines — SUBSTATION
Substation Design
FrameAI Substation automates the documentation and arithmetic for substation design up to 400 kV. IEEE 80 grounding grid calculations (touch/step voltage, mesh voltage, Schwarz equations), busbar rating per IEC 60871-1, equipment specifications per IEC 60076/IEC 62271, and single-line diagram generation — so your engineers focus on the engineering, not the spreadsheet.
FrameAI offers all disciplines as individual plans or bundled in cost-effective packages. View pricing →

Worked Examples
"33/11 kV primary substation: IEEE 80 mesh voltage 382 V < limit 599 V. Touch voltage 287 V < 453 V. 19 conductors, 50 × 5 mm copper, GPR = 1 840 V. PASS."

"Busbar: 80 × 10 mm aluminium, I_sc = 31.5 kA for 1 s. Derating: 50°C service (×0.92), grouping 3-in-row (×0.88) → I_rated = 1 420 A — PASS for 1 250 A feeder."
