Consider the two loads in the
circuit in (Figure 1). Load #1 (L1) absorbs S = 56 VA at a lagging
power factor of pf = 0.61. Load #2 (L2) absorbs P2 = 56 W and Q2 =
1 VAR of power. If these loads are powered by a V = 425 V−rms ,
60-Hz source, what impedance needs to be added to the circuit in
order to raise the source's power factor to unity? Express your
answer in rectangular...

VO) L1 L2 Line VO LI Power Calculations Learning Goal: In this tutorial, you will practice the calculation of power in circuits containing loads, including the effects of non-ideal transmission lines, and practice how to improve the power factor for an entire system. Many appliances (eg., hair dryers, coffee makers, and refrigerators) and industrial loads are powered by AC sources. The ability to be able to calculate their power needs is important in a number of situations. Before completing this...

Problem 3. Two three-phase generators supply a three-phase load through separate three-phase lines. The load absorbs 30 kW at 0.8 power factor lagging. The line impedance is (1.4 + j1.6) 12 per phase between generator G1 and the load, and (0.8 + jl) 2 per phase between generator G2 and the load. If generator G1 supplies 15 kW at 0.8 power factor lagging, with a terminal voltage of 460 V line-to-line, determine: 1. The voltage at the load terminals. 2....

1 A single phase AC system Consider a single phase AC distribution system in which there a single home connected to a 10kVA service transformer. Let’s assume that the primary of the distribution transformer can be modeled as an ideal 240V (rms) AC source and that the effective impedance of the transformer is 2% resistance and 3% reactance. (See lecture notes for converting % to Ohms). Connected to the secondary of the transformer is 200 ft of #6 AWG aluminum...
