It’s important to note that a CT’s accuracy class is not the knee point. The accuracy class is shown in terms of a C rating. For example, a 10P20 C400 CT rating means the CT needs to develop 400V across a 4-ohm burden at 20 times over current.

WebIn fact, this standard defines two knee points, one for air-gapped core CTs (ANSI 30º), the other for non-gapped CTs (ANSI 45º). For CTs with an air gap, the knee point is the point where the tangent line to the excitation curve forms a 30º angle. For CTs without an air gap, the knee point is where the tangent line forms a 45º angle.
