A500mva, 220kv/24kv, three phase y-δ transformer has an equivalent series impedance of 1 + j5 ω per phase referred to the high-voltage side. the transformer is supplying a three phase load of 500mva, 0.85 power factor lagging at a terminal voltage of 24 kv (line to line) on its low-voltage side. the primary is supplied from a feeder with an impedance of 0.5+ j1 ω per phase. determine the line-neutral voltage in kv across the load when it is referred to the transformer high side voltage.
