A three-exhibition transformer rated 11 MVA, 115kV/13.8 kV has per-exhibition succession impedance of j0.081 per part. The transformer is alike to a lacking arrangement course which can be represented by a succession impedance per exhibition of (0.02 + j0. 10) per part on a sordid of 10 MVA, 13.2 kV. The course victuals a balanced three-exhibition attack rated 6.3 MVA. 13.2 kV. delay behindhand government content 0.73. Draw an equiponderant tour of the classification indicating all impedances in per part. Choose 9 MVA. 13.2 kV as the classification sordid at the attack. Delay the voltage at the elementary cause of the transformer held trustworthy at 115 kV. the attack at the receiving end of the course is severed. Find the voltage habit at the attack.
