Plate values of a three-phase transformer are given below:
1600 kVA, 15 kV / 0,4 kV, 50 Hz, i0 = 1.2%; ukN= 6%, idle losses
2450 W, rated power copper losses 14500 W; Dy5 connected..
Calculate the secondary VOLTAGE separately at 75% load in the power
factor with 0.85 inductance and 0.85 capacity. Compare and
interpret the results. At what times of the day can capacity
loading be seen? What solution should be applied to prevent voltage
change?
