A 525 V to 110 V, 50 Hz, single phase transformer has a no-load current on the HV side, of 0,5 A at a power factor of 0.36 lagging. Answer the following questions regarding this transformer: 3.1 If a load current of 24 A flows on the LV side, at a power factor of 0.8 lagging, find the value of the primary current and the power factor. State the assumption and sketch the phasor diagram representing this situation. (10) 3.2 Determine the values of Rcore and Xmag and sketch this part of the transformer’s equivalent circuit and label it with the variables.
