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 MATLAB ^TM. | Numerade
