Question

Given values are in bold. 

The test results on a 100 KVA, 10000/1000 V, Y-Y 3– 4 transformer are shown below. Open circuit test on the low-voltage side Vline_oc = 500 V Iine_0c = 4.0 A P34 _0c = 1000 w Short circuit test on the high-voltage side Vline_sc = 1500 V Itine_sc = 2.0 A P30 _sc = 1200 w a) Find the per-phase equivalent circuit referred to the low-voltage side. b) Find transformer's voltage regulation when a balanced Y-connected 34 load of Z = 100 + j200 N per-phase is connected to the transformer. Assume the rated line voltage of 10,000V is applied to the primary.
