Question
Primary star connected three-phase
operating at 200kVA power, 15/0.4 kV 50 Hz
frequency
It has been observed that the transformer
draws 550 W in the experiment performed
when it is idle. of the transformer
the relative open giant current i0 = %1, 9.
a) Iron and magnetizing current, no-load
power coefficient and no-load draw
Calculate the reactive and active power.
b) Calculate the iron resistance and
magnetization reactance of the transformer.
