A 500/100 V, two-winding transformer is rated at 5 kVA. The following information is available:
A. The maximum efficiency of the transformer occurs when the output of the transformer is 3 kVA.
B. The transformer draws a current of 3 A, and the power is 100 W when a 100-V supply is impressed on the low-voltage winding with the high-voltage winding open-circuit.
Find the rated efficiency of the transformer at 0.8 PF lagging. Verify your solution using MATLABTM.
