A certain distribution transformer has nameplate data as follows:
power rating 75KVA
Voltage Rating 7200VAC/240VAC center tapped on the secondary for 240/120 VAC
impedance=4
It is desired to know the design impedence referred to the primary and to the secondary for basic engineering calculations and analysis
a. solve for the transformer impedance referred to the primary
b. solve for the tranformer impedance referred to the secondary
