The primary conductor in Figure 10.2 is one phase of a three-phase transmission line operating at \(345 \mathrm{kV}, 600 \mathrm{MVA}, 0.95\) power factor lagging. The CT ratio is \(1200: 5\) and the VT ratio is \(3000: 1\). Determine the CT secondary current \(\mathrm{I}^{\prime}\) and the VT secondary voltage \(\mathrm{V}^{\prime}\). Assume zero \(\mathrm{CT}\) error.
