Extracted text: O A CT of nominal ratio 1000/5 A is operating with total secondary impedance 0.4+j0.3 Q. (1 At rated current, the components of primary current associated with the core magnetizing and core-loss effects are respectively 6 A and 1.5 A. The primary winding has four turns and secondary winding has 800 turns. Calculate the ratio error at the rated primary current.
