Q: i know that megger is used in marine.but how its been used and please give me other megger application in detailedthanks for answer: In electrical testing we megger equipment. A ac voltage 600 volts is induced one a piece of electrical equipment like a transformer and the impedance is measured. The megger measured AC resistance/impedance vs normal dc resistance that volt meter measure. The higher voltage gave a more accurate measure of impedance. Equipment with defective insulation, would have a lower impedance.

Q: Downstairs 4 outlets and 4 of the lights stopped working. One of the outlets that doesn't work has the top plugin socket working but the bottom one doesn't. Also 2 lights still work even though they are in rooms where the sockets don't work. At the time we did have two computers running from the outlets and maybe some other electrical stuff. When the electrical went out we heard electrical sparking sounds.Then like a couple months later it happened again but upstairs. The lights and outlets stopped working in 2 bedrooms and the bathroom. I don't think we had very much electrical equipment plugged in just maybe a hair straightener.If I reset the breaker the switch will move to where its supposed to be but nothing happens.How much money should I have on hand for the electrician approximately? $200? $1000?: Other people here have explained some of the possible causes but your question is about money. If you have $400 on-hand, it's going to be plenty enough. It may go as low as $150. The easier you make it for the electrician, the smaller the bill will be. Furniture in front of the outlets, all those boxes under the circuit panel and the painted-on cover plates will slow him down and cost you money. Something is wrong in one of those boxes.

Q: I work on a plant where my workers have to trouble shoot low DC control voltage circuits besides high voltages ac running machines which are operated by inverters as well as from direct ac powerNeed a document or some tips to prevent electrical shocks and for electrician guidance: Work only in dry environments. No water on the floor. Plug AC powered test equipment into a GFCI protected circuit. Really no safety issues on DC voltages under 50V. Only handle electrical leads with one hand. Keep the other in your pocket. Rubber mats to stand on. Rubber gloves worn inside leather gloves Face shield and arc-flash rated clothing when working on anything over 50VAC.

Q: Im doing a report and I've looked jzt about everywhere and i cant find the answer to this question, please help: Population below poverty line: 21 % (2002)

Q: whats the correct procedure if you found a piece of faulty electrical equipment?: Depending on what it is and where it is at, lock it out and tag it out, then notify your boss. If you know nothing about lock outs, notify your boss and Maintenance. Wingman

Q: ???I recently went into a century tel building and was VERY interested. Does that have anything to do with what an electrical intrumentation technician does? If not please explain to me the difference between some one that is an electrical instrumentation technician would do, and what someone that works at century tel would do. I know this is a lot but Im planning for a major, and after that a career.Thanks!!!: You don't have the necessary qualifications for either immigration or temporary employment visa to Canada (or the US, for that matter). Instrumentation techs lack sufficient education and skill levels. You would need at least at bachelors, preferably masters, degree in Instrumentation Engineering to start with.

Q: exactly 5 min later:a- Would it damage the power grid?b-Would sudden surge after 5 min create even a bigger loss in energy than what was saved in that 5 min period??I am not an electrical engineer? I keep hearing that sometimes turning off an energy source for short term does not really save any energy? Is that true?Thanks alot.Could you help me with these 2 points?: Yes, in this extreme case, it may damage (BOE calculation: 2 million x ~500 watts: ~1 billion watt) if they are on single grid. In many of equipment (motorized) start-up losses are significant. So, you may end-up with little saving and a big grid failure. But if you leave aside such extreme situations, it is always good to turn off electrical equipments even for a short gap. And just to add, beware of leaking currents (e.g. not disconnecting appliances from the power plug) which are bigger concern.

Q: I plan to major in electrical engineering. I wanted to know if the stuff I learn there will allow me to do things like fix machines and stuff.I picked this major because I wanted something I can use at home: definitly after four years of B.E. programe in ELECTRICAL ENGINEERING you will be able to design circuits and erect electric connections at your home. it depends fully on how you study this subject you need to correlate with practical scenario you must try to experiment things at home. If you pursue this course with full aptitute and involvement i am sure you will achieve wat you wanted to use at home and also for the nation. ALL THE BEST ENGINEER!
