Answer Posted / thowsif_emerson_csm team
The knee point
is a ten percent ratio error between the
primary input current and the corresponding secondary
output current.
The saturation point involves determining the secondary
voltage necessary to drive the measured current through the
impedance of the secondary circuit.
