Please give correct answers to the following question:
A. Of the following, which are 4 advantages of a higher power factor while still supplying the same load (power factor correction)?
(Note: my answers: 1,5, 6,8 & score is 2/4, which means 2 answers are wrong)**
- Less resistive losses in the transmission lines
- Higher source current
- Larger cable diameters for power transmission
- Lower source voltage
- Smaller cable diameters for power transmission
- Lower source current
- More resistive losses in the transmission lines
- Higher source voltage

a) A single phase 240V 50Hz supply is supplying a power to a load which consist of 500 resistance and 0.3H inductance through a cable which has an effective impedance of 1+j2 0. The equivalent circuit of the single-phase system is shown in Figure Q1(a). Zcable=1+j2 I Load 5092 240V 50Hz Supply V Load 0.3H Figure Q1(a): A single phase system. i. ii.

Please answer question B
Expert Q&A The design of any power transmission system is very sensitive to the magnitude of the current in the lines as determined by the applied loads. Increased current result in increased power losses in the transmission lines due to the resistance of the lines. Every effort must therefore be made to keep current levels at a minimum. The process of introducing reactive elements to bring the power factor closer to unity is called power factor...

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...
