Figure 3.

A 3 D scatter plot displays data points categorised into seven classes, plotted across saturation flux, unsaturated inductance, and remanence factor.

The plot presents a three-dimensional scatter chart with the horizontal axis for saturation flux in webers, the depth axis for unsaturated inductance in henries, and the vertical axis for remanence factor in percent. Data points are grouped into seven distinct classes, labeled from class 0 to class 6, each with a unique marker style. The distribution shows that certain classes cluster at lower inductance and higher remanence factor values, while others extend across higher saturation flux and inductance ranges. The spatial separation of these clusters indicates variations in the underlying properties represented by each class.

Identified seven clusters which are separable in the feature-space: saturation flux $ϕ_{m, s}$ ⁠, unsaturated inductance $L_{m}$ ⁠, remanence factor $K_{r}$

Note(s): Transformer-specific characteristics can be generalized for each group
