A $45$ kVA three phase transformer $(2\mathrm{.}2$ kV : $4\mathrm{.}6$ kV $)$ is to be constructed from three single phase transformers. The transformers are connected as $\backslash (\backslash$mathbf$\{$Y$\}-\backslash$boldsymbol$\{\backslash$Delta$\}\backslash ).$ The transformer per phase impedance on the LV side is $\backslash ((2\mathrm{.}1+$j $23\mathrm{.}6)\backslash$mathrm$\{$m$\}\backslash$Omega $\backslash ).$

$($i$)$ Calculate the effective turns ratio of the $\backslash ($ Y $\backslash )-\backslash (\backslash$Delta $\backslash )$ connected transformer. Show your working clearly.

$($ii$)$ Determine the impedance of the transformer referred to its HV side.

$($iii$)$ Calculate the rated current on the LV and HV sides of the transformer and hence determine the power loss through the transformer when connected to a rated load.
