nsformer, and the supply power factor is unity. Determine :
(ⅰ) The load impedance.
(ⅱ) The load voltage.
(ⅲ) Voltage regulation(use Eq. 2.16).
2.20 Three , 200kVA, 210/210 V, 60Hz transformers are connected to form a , 2300/460 V transformer bank. The equivalent impedance of each transformer referred to its low-voltage side is . The transformer is connected to a feeders, the impedance of each feeder being . The transformer is connected to a source through feeders, the impedance of each feeder being . The transformer delivers full load at 460 V and 0.85 power factor lagging
