  ASSIGNMENT EE 445L/EE 433L Write your solution on a clean bond paper. Scan your answer and solution then send it to our group chat. Deadline of submission will be on March 17, 2018, Saturday, 12:00NN. Problem No. 1 The power factor of a certain inductive load is improved to 0.92 leading with the addition of a 50 kVAR bank of Capacitors. If the resulting supply apparent power is 200 kVA, determine: a.   The active/real power b.   The reactive power before power factor correction c.   The power factor before correction. Problem No. 2 The network shown in Figure below has a total active power of 2253 W. Assuming that the voltage supply has an angle of zero degree. Determine: a.   The supply current b.   The apparent power c.   The reactive power d.   The circuit power factor e.   The capacitance of the capacitor to be connected in parallel with the network to improve the power factor to 0.90 lagging, if the supply frequency is 50 Hz. Problem No. 3 The two loads in the circuit shown in Figure below can be described as follows: Load 1 absorbs an average power of 8kW at a leading power factor of 0.8. Load 2 absorbs 20kVA at a lagging power factor of 0.6.  a.   Determine the power factor of the two loads in parallel. b.   Determine the apparent power required to supply the loads, the magnitude of the current, Is, and the average power loss in the transmission line. c.   Given that the frequency of the source is 60Hz, compute the value of the capacitor that would Correct the power factor to 1 if placed in parallel with the two loads. Recompute the values in (b) for the load with the corrected power factor.
