But the tool’s real secret emerged when she double-clicked finch_core.log .
When she presented the design, her advisor called in industry experts. They ran their own simulations. The results matched PTDT’s outputs to within 0.3%. “This is impossible,” one said. “Who wrote this tool?” Power Transformer Design Tool
In the first hour, it asked her about winding arrangement, suggesting a novel interleaved disc design that reduced eddy losses by 18%. In the third hour, it generated a complete core stacking pattern, optimizing the mitred joints to suppress local hot spots. By midnight, it had output a full mechanical drawing, a bill of materials, and even a thermal simulation showing the hottest spot would be 6°C below the limit. But the tool’s real secret emerged when she
In the cramped, humming basement lab of Edison-Hawthorne University, graduate student Mira Vasquez stared at a blinking cursor. Her PhD advisor had just dropped an impossible project on her desk: design a 500 MVA power transformer for a floating wind farm substation—with 40% less core loss than current tech—in under three months. The existing methods meant weeks of iterative math, finite element simulations that took days to run, and a stack of IEEE papers taller than her thesis. The results matched PTDT’s outputs to within 0
And that’s how a dead engineer’s logic taught a new generation to build the electric grid of the future—one winding, one core, one honest question at a time.
That night, Mira found the miracle buried in a forgotten server directory. A retired engineer named Alistair Finch, who had worked for a now-defunct transformer manufacturer, had left behind a cryptic executable: .
