A distribution feeder provides service to a delta-connected load having the following phase currents: lab-208.32-18.19 1be138.892-151.788 1-131.94% 145.84 a. Draw the three-phase diagram and identify the phase and line currents, and line-to-line voltages. b. For the phase currents: i. Are they balanced or unbalanced? What is their sum? ii. iii. Obtain their sequence quantities. iv. What is the 0-sequence quantity? c. Obtain the line currents. For these currents: Are they balanced or unbalanced? What is their sum? ii. iii. Obtain their sequence quantities. iv. What is the 0-sequence quantity? d. Use what you have learned in the parts (a) and (b) of Problem 1 to answer the three questions (ii, iv) from part (b) for the following a-b-c quantities (calculations are not necessarily required): V. Unbalanced currents into a grounded-Y. Unbalanced currents into an ungrounded-Y. vil. Unbalanced line-to-line voltages. vi.
