The knee-point voltage will depend on the size and class of
the CT, and it can be very high on some CTs Be very
cautious, you will be working on
live equipment during the test.
Now you can just plot the current and voltage values on a
graph. This is the mag-curve of the CT. IEC classify the
knee point voltage as the point where a 10% increase in
voltage results in a 50% increase in current.
