A $3-$phase $50$Hz $200$km long transmission line has following distributed parameters per km: $1=0\mathrm{.}2$ohms, x$=0\mathrm{.}41$ohms, y $=3\mathrm{.}14$x$100$ mho. The sending end voltage is $220$kV$.$ Determine A$,$ B$,$ C$,$ D parameters of the line and hence determine the sending end current and receiving end voltage of the line under open circuit condition. Consider the line as long line.
