The primary conductor in Figure 10.2 is one phase of a three-phase transmission line operating at \(345 \mathrm{kV}, 700 \mathrm{MVA}, 0.95\) power factor lagging. The CT ratio is \(1200: 5\), and the VT ratio is 3000:1. Determine the CT secondary current \(I^{\prime}\) and the VT secondary voltage \(V^{\prime}\). Assume zero CT error.
