Knee point is the term comes under current transformer (CT)
It is a point in the Curve of voltage and current where if
there is 10% increment in voltage then there will be 50%
increment in current. This point shows the saturation of CT
core. For Protection CT knee point will be high as for
metering CT it will be less to save the meters.
