Answer / lakshmi

it is the votlage at which the curent transformer gets
saturated.

Answer / sunil

knee point voltage is voltage applied to secondary of
transformer at which 10% increase in voltage must not
increase 50% current

Answer / rajeshpandian

Apply the voltage to secondary in ct,which point magnetising
current increases 50 % rise of voltage 10%.taht is called
knee point voltage.If you increase the voltage after the
Knee point u get the abnormal magetising current.

IS there any special instructions to be taken while installing the tranformer.
