Question

A single phase transformer with 10 : 1 turn-ratio and rated at 50 kVA, 2400/240 V, 50 Hz is used to step down the voltage of a distribution system. The low tension voltage is to be kept constant at 240 V. find the value of load impedance of the LV side so that the transformer will be loaded fully. Find also the value of maximum flux inside the core if the LV side has 23 turns.

Step 1

The transformer is rated at 50 kVA. The full load current on the LV side can be calculated using the formula: \[ I_{\text{LV}} = \frac{\text{Power}_{\text{rated}}}{V_{\text{LV}}} \] Where: - \( \text{Power}_{\text{rated}} = 50 \text{ kVA} \) - \( V_{\text{LV}} = Show more…
