The toroidal current transformer of Fig. 11.19 has a ratio of 1000A/5A. the line conductor carries a current of 600A.
a. Calculate the voltage across the secondary winding if the ammeter has an impedance of 0.15 .
b. Calculate the voltage drop the transformer produces on the line conductor.
c. If the primary conductor is looped four times through the toroidal opening, calculate the new current ratio.
