Question $1$: A single phase transformer supplies a load through a short feeder. The transformer is connected to a voltage source. The system data are: Sr # $160$ kVA Xpri $2\mathrm{.}5$ohm Xmag $-3$kohm Rpi$-0\mathrm{.}50$ ohm Vsec $=380$ V Rsec $-0\mathrm{.}01$ohm Xsec$-0\mathrm{.}05$ohmRmag$-6\mathrm{.}2$ kohm Vload $375$V Pload$-64$kW Lfeeder $8$mi phad $=0\mathrm{.}85$ freq$-60$ Hz Zteeder $(0\mathrm{.}2+$j $0\mathrm{.}58)$ ohm$/$mi a$.$ Draw the equivalent circuit. b$.$ Calculate the load current. $20$ points $20$ points c$.$ Calculate the transformer secondary and primary voltage and $20$ points current. d$.$ Calculate the transformer magnetizing current and network $20$ points supply current and voltage. $20$ points e$.$ Determine the voltage regulation. Is it acceptable?
