A 3-phase transformer rated for $33 kV/11 kV$ is connected in delta/star as shown in figure. The current transformers ($CTs$) on low and high voltage sides have a ratio of $500/5$. Find the currents $i_{1}$ and $i_{2}$, if the fault current is $300$ A as shown in figure.

  1. $i_{1}=1\sqrt{3}A, i_{2}=0A$
  2. $i_{1}=0A, i_{2}=0A$
  3. $i_{1}=0A, i_{2}=1\sqrt{3}A$
  4. $i_{1}=1\sqrt{3}A, i_{2}=1\sqrt{3}A$
