Electrical energy involves power generation, transmission, and distribution. The latter two involve DC or AC lines with varying voltages. The largest known DC voltage is approximately 1 million volts. AC transmission lines employ voltages ranging from 66 kilovolts to several hundred thousand kilovolts. Since there are no high voltage DC lines in cities, the only concem is from high voltage AC lines to substations. These lines carry currents producing circumferential magnetic fields which exceed the IEEE standard (ahout 4 microWehers/square meter for magnetic flux density and 0 03 W/kg for S AR). These lines produce high intensity electromagnetic fields. The most recent concem has been the magnetic fields from high voltage transmission lines in residential areas. Possible effects of the magnetic fields are malignant tumors and genetic mutations. The voltage in residential areas is constantly increasing because of the rising number of lines, the higher voltages being used, and the number of homes being built near them. It seems that the highest exposure times correspond to the times of day that the electrical power consumption is the highest. The easiest way to minimize the magnetic flux density levels to individuals is to build homes such that a grounded, metallic, mesh screen is installed on the roof and in the walls while the house is being constructed. A real estate agency hires a contracting firm to build a subdivision in a certain rural area. The job is worth millions of dollars to the firm. When the contractors visit the site they see that there are high voltage power lines in great numbers running over it. They approach the real estate company with a suggestion of installing the protective mesh in the homes. After discussing the price increase involved, the real estate agency refuses to pay for the protection. Should engineers employed by the contractors recommend that the contractors build the homes without the mesh or should they absorb the cost themselves? What about homes that are already built? If power companies put high voltage power lines in an already existing residential area, on who would the burden of cost fall on? Question 1: Question 2: Ethies Scenarios 1. You are a government employee, and there is a $35,000 limitation on contracts that can be approved without a formal open bid solicitation process. Would you divide project A, which is greater than $35,000 into two projects of S20,000 cach so you can use the contractor of your choice? 2. A vendor has requested a meeting with you, and would very much like to do business with your company. Should you accept a modest lunch (<$15) paid for by the vendor? An expensive lunch ($20y? Drinks after work? A vacation? A pair of tickets to the Superbowl? 3. What do you do if you are working in an office near the CEO of your company and learn that she is guilty of malfeasance? 4. You are a senior software systems expert, hired by NewSoft, a start-up company, to help in the development of a new product, You soon learn that the new product is based on proprietary software for which NewSoft does not have a license. You assume that this was some sort of mistake and speak to the company president about the matter, He assures you that the situation will be rectified. Some time passes and nothing has happened except that you find other instances of the same practice, What do you do? Electrical energy involves power generation, transmission, and distribution.
