I have worked this out and compared to other colleagues and they are getting different answers that do not match up to the turn ratios, and I am getting tired of this problem.
A single-phase distribution transformer supplies four houses. The maximum load is 12 kW at a power factor of 0.78 (lagging). The load voltage is 235 V. The transformer rating is 20 kVA, with a primary voltage of 7.2 kV, a secondary voltage of 240 V, and a leakage reactance of 12%. Calculate the transformer supply voltage.
I've worked it out but I'm not sure its correct because you are given a leakage reactance in the problem, but it does not need to be used.
