A Current Transformer (CT) has a turns ratio of $$600:5$$ and a magnetizing curve as shown in Figure 3.3 below. The total burden impedance is $$(5+j2)?$$; the secondary leakage impedance is negligible. Assume that the impedance angle of the magnetizing branch is $$70^{?}$$. The current through the burden is measured by the relay as $$37.2?32^{?}\mathrm{A}$$. What is the actual current through the primary conductor of the CT?
