Three single-phase transformers are connected to

Three single-phase transformers are connected A-A to provide power for a three-phase Y-connected 200-kVA load with 0.8 lagging power factor and 80-kVA single-phase light load with a 0.9 lagging power factor. Tc Assume that the three single- phase transformers have equal percent impedance and equal ratios of per-cent reactance to percent resistance. The primary side voltage of the T = Tas AO- bank is 7620/13200V and the secondary side voltage is 240V. Assume that the single- phase transformer connected between phases b and c is To.30 + Van- Bo rated at 100KVA and the other 80 KVA 0.90 PF Te Toe two are rated at 75 kVA. To Determine: Co 1. The line current flowing in each secondary-phase wire 2. The current flowing in the secondary winding of each transformer 3. The load on each transformer in kVA "A- leeleee 1elle
