Ac Mitigation

Aaron Castloo Speech 4 10/27/09 SPEAKERS CHOICE science/Technology OBJECTIVES Organization: Topical prevalent Purpose: To certify Specific Purpose: To affirm my audience of AC temperance. commutation Idea- I am overtaking to inform you of AC mitigation, victimization DC contemporary and zinc mats to prevent it, and the resort hazards understructure it. I. Attention Getter: AC mitigation, what is that? I am going to inform you of what AC mitigation is, using DC to correspond clothing away, and the gum elastic hazards involved. a. Electrical fields and the effect that they pass on lines is a very well-established science. b. Anyone touching a valve or opposite aboveground object connected to the pipeline mogul 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/ scoke: a. AC mitigatio n is the preventing of alternating current to cause wearing to metal, DC current and Zinc matting eliminate the problem, and caoutchouc is always a concern. BODY I.AC Voltage from transformer lines cause AC Induced Voltage. Some of the factors that influence induction include throwaway and non-peak load factors. a.High power transformer lines put off 15 to 30 volts AC onto any border metal objects.

b. pillar groundings for these volumed transformer systems send AC into the earth too. c.Also surrounding pipelines can transport AC current onto your pipeline. Transition: entirely this AC D C TALK…now lets talk nearly how to p! revent it. II.DC current is used to reverse the infixed hunt down of electrons to protect the pipeline and zinc matting also helps. a. Rectifiers are set up every so umpteen 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...If you want to get a full essay, order it on our website: BestEssayCheap.com
