Class PS/ X CT: In balance systems of protection, CT s with
a high degree of similarity in their characteristics are
required. These requirements are met by Class PS (X) CT s.
Their performance is defined in terms of a knee-point
voltage (KPV), the magnetizing current (Imag) at the knee
point voltage or 1/2 or 1/4 the knee-point voltage, and the
resistance of the CT secondary winding corrected to 75C.
Accuracy is defined in terms of the turns ratio.
