Current transformer clustering selection

Cluster	Color	Symbol	Description
$C_{0}$	Purple	◊	Material with higher relative permeability $μ_{r}$ and lower saturation flux $ϕ_{m, s}$
$C_{2}$	Light blue	X	Material with lower remanence factor $K_{r}$ ⁠, typically including transformers with thinner hysteresis
$C_{3}$	Turquoise	□	Larger cores, material with higher saturation characteristic $ϕ_{m, s}$ ⁠, thin hysteresis
