Consider a one-phase non-ideal transformer with a core.
It is rated 100/15 kV, 50 MVA at 50 Hz.

It has the following parameters:
Primary side wiring resistance 2 Ω
Secondary side wiring resistance 0.03 Ω
Primary side leakage reactance 2 Ω
Secondary side leakage reactance 0.02 Ω
Magnetizing reactance Xm= 1.5 MΩ
Iron core loss resistance Rc=6 MΩ
Calculate the active power drawn from the grid during an open
circuit test
