saturate at that point. this point is knee point voltage.

Answer / sumit kumar

the knee point of voltage of ct is the that point at which
cts enters into saturation state.

Answer / santosh kumar gupta

knee point voltage is that where the rising voltage will be
taken a constant amplitude at a time but that time current
will not be taken constant, that voltage called knee point
voltage.

Answer / praful nandankar

It is that point after which the voltage becomes
constant.There will be no effect of voltage on current.

Answer / mageshwaran

the point of saturation i.e, 10 percent increase in
voltage gives 50 percent increase of current is known as
knee point voltage
