Extracted text: The following data are taken on a 40 KVA, 2200/220 - volt, 60 – Hz Transformer: Open - circuit test on low side: P= 220 W, I= 5.2 A, V=220 V Short- circuit test on high side: P = 397 W, I = 18.18 A , V = 40 V Calculate: 1. Magnetizing current component Im2 (referred to HV side) 2. Core loss current component Ict (referred to LV side) 3. The parallel branch parameters Rei and Xml referred to LV side 4. The series parameters Reg2 and Xeq2 (referred to HV side) 5. The efficiency of the transformer at full loading with load power factor = 0.8 lag. %3D
