A single-phase transformer single phase 1.4 kVA, 415V / 240. Load consumes 1.4kVA, lagging power factor 0.9 when fed with 240V Connected to a load R=33.78 and L=73.2mH. Determine the primary voltage magnitude required to produce rated secondary voltage under the above load condition. Calculate the primary and secondary currents for the calculated voltage. Calculate the input and output power and efficiency. R1=1.20hm R2=0.6Ohm L1=7mH L2=3mH RO=10000hm LO=4000mH
