You are working as an electrician in a large steel manufacturing plant, and you are in the process of doing preventive maintenance on a large DC generator. You have megged both the series and shunt field windings and found that each has over 10 M to ground. Your ohmmeter, however, indicates a resistance of 1.5 across terminals S1andS2. The ohmmeter indicates a resistance of 225 between terminals F1andF2. Are these readings normal for this type machine, or is there a likely problem? Explain your answer.
A power plant produces 1000MW to supply a city 40km away. Current flows from the power plant on a single wire with resistance through the city and returns via the ground, with negligible resistance. At the power plant the voltage between wire and ground is 115 kV. Determine: (a) the current in the wire, and (b) the fraction of the power lost in transmission.
A string of suspension consists of four (4) units. The Voltage between each pin and earth is 0.12 of the Self-Capacitance of the unit. The Voltage between the Line Conductor and earth is 135KV. Find the Voltage distribution across each unit and the String Efficiency
When electricity is transported from a power station to a city, the line voltage (relative to ground) is usually on the order of several hundred thousand volts. A power line cable has a radius of a = 2.0 cm, is made of aluminum with a resistivity of ρ = 2.7×10−8 Ω ⋅ m, and spans a distance of l = 100 km from a power station to a city. The city consumes 100 MW of power (so I2RL =100MW). (a) Find the resistance of the power cable between the station and the city(i.e.,between points A and B). (b) Suppose that the line voltage ∆VBC = 120 V. i. How much current is required to flow through the power line to deliver 100MW of power to the city? ii. How much energy is lost as heat between points A and B? (c) Suppose that the line voltage ∆VBC = 300 kV. i. How much current is required to flow through the power line to deliver 100MW of power to the city? ii. How much energy is lost as heat between points A and B?
For an electrical component, the formulas for charge and voltage are given below. A is 9 coulombs, B is 12 seconds, C is 3 volts, and D is 24 seconds. Give the current of this component at t1 = 8 sec. You must round your answer to the nearest thousandth and give your answer as an integer followed by the appropriate metric prefix and the letter that represents the units of current.
