Current Transformer (CT)
Function of a CT
used to step down line current to make it easier to measure by current measuring instruments like an ammeter.

-
When the primary has a large current rating, the primary winding may consist of a straight conductor passing through the center of the magnetic circuit.

Knee Point Voltage (Vkp)
-
The magnetization curve classified 3 zones. Magnetizing, linear, pre-saturation, saturation curves.

-
In saturation, there is no flux change when the primary current changes
