6) Barry power station supplies Mobile with about 1 GW of electrical power. (a) If the transmission lines operate at 300 kV, what current would be carried by the lines? (b) The power station is located about 30 km from Mobile. If the combined cross sectional area of the aluminum transmission lines is 20 cm^2, and the resistivity of aluminum is 2.65 × 10−8 Ω · m, what is the resistance of the wire? (c) How much power would be lost as heat in the transmission lines, if they had to carry the current found in part (a)? Express your answer as a fraction (percentage) of 1 GW.
A portion of a power system is shown in Fig. which also shows the ratings of the generators and the transformer and their respective percent reactances. A symmetrical short circuit appears on a feeder at F. Find the value of the reactance X (in percent) such that the short-circuit MVA does not exceed 300MVA.
The single line diagram of a small power system isshown in Fig. 1. The corresponding reactancediagram, with reactances in per unit, is shown inFig. 2. A generator with emf equal to 1.25∠0° perunit is connected through a transformer to highvoltage node 3, while a motor with internalvoltage equal to 0.85∠ − 45° per unit is similarlyconnected to node 4. Develop the nodaladmittance matrix for each of the networkbranches and then write the nodal admittanceequations of the system.

An electrical motor is supplied from a three-phase ,50 Hz, 410 V system on-board a LNG carrier .When connected in star , it takes a line current of 35 A at a power factor of 0.66 leading. The LNG carrier arrives at port and the motor is subsequently used for powering a container crane It is now connected in delta and is supplied on-shore .Determine for this motor when it takes 64 A at 310 V, from the on-shore supply: 2.1 The power factor of the motor 2.2 the frequency of the supply The motor is returned back to its initial supply and now connected with a new motor in parallel . The new motor is connected in delta and it takes 48.216 kVA at a power factor of 0.77597 lagging with a supply of 50 Hz, 410 V system. Determine for this new arrangement : 2.3 The power factor 2.4 Apparent power taken 2.5 True power taken 2.6 Reactive power taken
Regional Maritime University (RMU) campus has 200 classrooms and 400 faculty offices. The classrooms are equipped with 12 fluorescent tubes, each consuming 110 W, including the electricity used by the ballasts. The faculty offices, on average, have half as many tubes. The campus is open 240 days a year. The classrooms and faculty offices are not occupied an average of 4 h a day, but the lights are kept on. If the unit cost of electricity is GH₵ 0.082/kWh, determine how much the campus will save a year if the lights in the classrooms and faculty offices are turned off during unoccupied periods.
