Step 1: Answer 3.1 Four methods used to reduce losses in a transformer are: • Laminating the core to reduce eddy current losses. • Using high-grade silicon steel for the core to reduce hysteresis losses. • Using conductors with a large cross-sectional area for windings to reduce copper (I^2R) losses. • Optimizing the design of the core and windings to minimize leakage flux. Step 2: Calculate the transformation ratio (3.2) Given: Transformer rating S = 30 kVA Primary voltage V_1 = 2200 V Secondary voltage $V_2 = 250 V
