Q:How do I find someone to auction electrical engineering equipment?
There is a good chance that if it is old equipment, it won't be worth much. There is also a chance that some of the old amplifiers and circuit board materials contain hazardous material or chemicals that need to be disposed of properly. A first step would be to take the parts numbers off the equipment and enter them into google. There is a good chance that the stuff you have is not going to be worth anything, if there are pieces that are worth much you could sell those, and then ship the worthless stuff off to a electronics recyclers.
Aiurcraft have electrical genarators on them, powered by the engines, those generators, provide power to aircraft electrical systems. You would be working on those electrical syatems, IE: the generators, the power transformers and wiring that provide electrical power to the aircraft. Aircraft also have heating and cooling systems that provide warm air and cold air to different parts of the aircraft. You would be working on those systems. Basicly you job is to do scheduled functional checks of the systems, to make sure they work, to repair any problems found found, replace faulty equipment in the aircraft.
Q:Please help me. i cant find anything about it.?
I can't find out if you don't say what equipment it is.
Q:Who can tell me how ski lifts and snow making equipment work?
Your electric drive motors run on high voltage. Three phase 480v. All of your controls and safety systems run on low voltage. Battery powered, 24 or 48 volt. This is so that the lift can operate properly in the event of a power outage that cuts power to the drive. Lifts have backup drives, usually a diesel generator that can supply power to the electric drive motor, or an actual gas or diesel motor that can be coupled to the gearbox and drive the lift itself. Controls are usually a programmable logic control that monitor proper operation of different components of the lift and through a series of relays send power to the drive. Snowmaking is as aforementioned powered by large electric pumps and air compressors. Air and water are pumped usually from a central location and piped around the mountain to hydrants. Here, the snow guns are connected to the air and water. Some types of guns simply blow the water and air to make snow, while some have motors on them. These plug in to electrical pedestals, high voltage, that are located at the hydrant locations. These power large fans that help disperse the water and also control oscillating guns.
Q:what dose watt indication of electrical equipments means?
a watt is how much power an electrical Appliance will draw. current x voltage will give you what power is required. e.g. if ur appliance runs at 230v and is rated for 10amps then it will be rated at 2300watts. This is what electric companies use to see how much to charge you as they will charge by the KWatt per hour. 1 watt 1 joule per second
Q:My boyfriend disrupts electrical connections with his presence?
Wrong again, Eri. Physics degree(s)Should I say, wow here? Ok.wow. This proves a degree doesn't always mean something. I don't know if it has anything to do with 'aliens' but I DO know that it is a condition that is not common, does happen, and is extremely dangerous to our sensitive electronic equipment. As an RF engineer, we had people that could not enter our shelters, because of their 'power' to throw off sensitive equipment. In a lot of places like an ATT substation you will see a copper rod outside. It is meant for people to ground themselves before entering the shelter (and for static discharge). We have had employees that could not climb towers due to their electrical presence. Your bf just has that 'electric' personality. If aliens were in fact involved, it would be interesting to see how they did it.
Q:What step down converter must i use ( READ DETAILS PLZ)?
DC9V @ 850mA is 7.65 watts. Your stepdown transformer can handle 230 watts so a measly 7.65 watts is no problem for it. Use it with confidence. Or buy a replacement AC adapter with an input of 240vAC, output of 9vDC for a lot cheaper. As long as the adapter output is rated for 850mA or higher, it will be good. (Make sure the polarity is correct, as well as the physical fit of the coaxial connector.)
Q:House wiring responsibilities?
You should never work on a circuit that's live or has electricity in it. Always make sure the circuit breaker is shut off and is labeled as being worked on so somebody else doesn't turn it on. Other than that, do the work according to the electrical code in your area.
Q:If I ordered goods online at a cheap price because the retailer made a mistake, do they have to send me it?
Depends on what you mean by discount error If you used a promo code that is not supposed to be valid on the item you purchased, then NO, he does not have to honor your order just because the system accepted it. On the other hand, if he has the item listed incorrectly (ie, $10 instead of $100) than yes, he should have honor it. Make sure to look for anything on the website that says something along the lines of prices subject to change which could be used as a loophole. Either way though, he may not charge you more without your permission. In Califonia, if an item in a store is marked a certain price, it is actually illegal for the store to try to charge you more when you attempt to purchase the item. However, based on the fact that you may not even be in the same state as the store, things get a little murky. The best answer is simply to cross your fingers, as the internet is really a grey area. UPDATE: In follow-up, no they absolutely cannot demand that you send it back after you've receieved it. Nor can they try to charge you more afterwards. If it gets shipped, then it's yours to keep!
