Electrical Heating Unit

The conversion of electrical energy to heat energy is known as electric heating. The heating system that converts the electrical energy to heat energy for various application is called electrical heating unit. Electricity is employed as the firing mechanism in electric heating systems, which transforms electric current to heat. Electric heaters have heating elements in the form of electric resistors.

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.

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?
