Demos on transformer digital twins.
-
Duval triangle under uncertainty
One DGA result in Duval Triangle 1, and the cloud of diagnoses it could equally have meant. Push the relative measurement uncertainty from 5 to 35 percent and the point starts crossing zone boundaries.
-
Duval pentagon under uncertainty
The same question in five gases. One point in Duval Pentagon 1 and 2, and the region of diagnoses that the laboratory error bar really covers.
-
A year of top-oil and hot-spot temperature computed from a load profile, and four ways to propagate the uncertainty in it into the remaining life of the insulation.
-
One transformer, one thermal model, five jobs: describe the state, diagnose a cooling fault, forecast the next 48 hours, choose between dispatch options, and close the loop.
-
Where the water actually sits. The same reading in ppm means very different moisture in the paper depending on temperature, and drying the oil barely touches the paper at all.
