For a 7.96-kV : 39.8-kV, 60 Hz, 10 MVA single-phase transformer with the high voltage winding open-circuited, a voltage of 7.96 kV is measured with the resultant current 17.3 A and power is 48.0 kW. The low-voltage winding is then short-circuited and a voltage of 1.92 kV is measured with a current of 252 A and a power of 60.3 kW. a. Calculate the parameters of the equivalent circuits as referred to the transformer high-voltage winding and draw the corresponding circuit. b. Calculate the equivalent-circuit parameters as referred to the transformer low voltage winding and draw the circuit. c. With the transformer carrying rated load and rated voltage at its low-voltage terminal, calculate the power dissipated in the transformer.

What horsepower must an electric motor develop to operate a pump that pumps water at a rate of \( \mathbf{2 4} 000 \) liters per hour ( \( \mathrm{L} / \mathrm{h}) \) up a vertical distance of 50 m if the efficiency of the pump is 90 percent? The gravitational force on 1 L of water is 9.78 N . \% Efficiency \( = \) Pout/Pin \( 24000 \mathrm{~L} / \mathrm{hr} * 9.78 \mathrm{~N} / 1 \mathrm{~L} * 50 \mathrm{~m} \) Ans. 4.86 hp
