Question 2

Question 1 On figure 1 below is a single-phase ring distributor fed from point O at 400V, 50HZ. Loads of 300A at 0.75 power factor lagging, 180A at 0.6 power factor lagging, 120A at unit power factor and 300A at 0.7 power lagging are drawn at load points A, B, C and D respectively. The impedances per phase for the distributor sections OA, BC and CD are 3+j2Q, section D0 is 1+j2Q and section BC is 2+j3Q. a. Find the currents per phase along various sections of the distributor b. Determine the power drawn from the source Figure 1 Question 2 On figure 1 below is load distribution on a two wire d.c. distributor fed from one end from a 400V from dc surce. The distributor has a 0.27cm? cross sectional area of each conductor. Assuming lengths LaB=75m, Lec=100m and Lco=50m, while a resistivity of 1.78µ2cm for the wires, determine: a. currents along various sections of the distributor b. the two core resistances of each section of the distributor С. the voltage at each tapping point B 12A 15A. 20A Figure 2
