Ac Mitigation

Aaron Castloo Speech 4 10/27/09 SPEAKERS CHOICE Science/Technology OBJECTIVES Organization: Topical world-wide Purpose: To inform Specific Purpose: To inform my audience of AC mitigation. Central Idea- I am waiver to inform you of AC mitigation, using DC current and zinc mats to prevent it, and the rubber hazards behind it. I. Attention Getter: AC mitigation, what is that? I am going to inform you of what AC mitigation is, using DC to go against wearing, and the safety hazards involved. a. Electrical fields and the effect that they have on pipelines is a very well-established science. b. Anyone touching a valve or other(a) aboveground object connected to the pipeline might be subject to being electrically shocked. II.Orienting Information a. These problems with AC Mitigation are solved with the newest technologies in science. III.Central Idea/ see: a. AC mitigation is the preventing of alternating current to cause corrosion to metal, DC current and Zinc matting eliminate the problem, and safety is always a concern. BODY I.AC Voltage from transformer lines cause AC Induced Voltage. Some of the factors that influence induction include point in time and non-peak load factors. a.High power transformer lines put off 15 to 30 volts AC onto any ring metal objects.

b. loom groundings for these large transformer systems send AC into the earth in addition. c.Also surrounding pipelines can bring AC current onto your pipeline. Transition: all(a) this AC DC TALK…now lets talk more or less how to prevent it. II.DC Current is used to reverse the rude(a) catamenia of electrons to protect the pipeline and zinc matting also helps. a. Rectifiers are set up every so some(prenominal) miles that take AC current and turn it to DC current. b. DC current on a pipeline reverses the natural flow of electrons causing the pipeline to be cathodically protected. c. Zinc matting and magnesium anodes at PI...
