Draw the single-phase equivalent circuit for the motor (an cmf in series with inductive reactance labeled zM) and its connection to the voltage supply described in Probs. 1.16 and 1.17. Show on the diagram the per-unit values of the line impedance and the voltage at the motor terminals on a base of 20 WA, 440 V. Then using per-unit values, find the supply voltage in per unit and convert the per-unit value of the supply, voltage to volts Probs. 1.16 If the impedance of each of the three lines connecting the motor of Prob. 1.16 to a bus is 03 + j1.0Ω, find the line-to-line voltage at the bus which supplies 440 V at the motor. Prob. 1.16 Determine the current drawn from a three-phase 440-V line by a three-phase 15-hp motor operating at full load, 90% efficiency, and 80% power-factor lagging. Find the values of P and Q drawn from the line.
