(b) In a transformer test, data from short circuit and open circuit tests of a 75-kVA, 4600-230V, 60HZ transformer are: Open circuit test data is referred to low voltage side Short circuit test data is referred to high voltage side Voc = 230V Vsc 160.08V Ioc = 13.04A Isc = 16.3A Poc = 521W Psc 1200W Determine (a) the magnetizing reactance and core loss resistance (b) the per unit equivalent impedance

What conclusions we come up with after doing open circuit test on single phase transformer.

formula for determining the power of a single-phase transformer

In a transformer that has 10 times more turns on the secondary side (side 2) than on the primary side (side 1), the magnitude of the voltage/EMF across the windings on the secondary side, E₂ will be... O a.... 10 times lower than the voltage/emf on the primary side, E₁. O b.... the same as the voltage/emf on the primary side. O c.... always zero regardless of the voltage on the primary side, E₁. O d.... 10 times higher than the voltage/emf on the primary side, E₁.
