- Q: I love the Transformers movies and games to death, but I've never ever been able to like the cartoons.I know they were somewhat popular, especially as the first Transformers game was a huge successplease add why you like/dislike it.thanks in advance
- I hated the old transformers cartoon movie with a passion. Mainly cause my ex used to watch it over and over and over again, and Cry at the optimus part every freakin time. By the time we broke up, I wanted all transformers things to die. I'm recovering slowly.
- Q: If a transformer rating 240vac 50hz being supplied by a source 240vac 60hz,will it get hotter than by 240vac 50hz source?
- Hard to say. higher frequency lower magnetization current lower copper losses but higher magnetic losses. It depends on specific construction of the transformer. Roughly I'd say no significant change in heat dissipation.
- Q: High-rise residential basement transformer noise is too large, how to solve, whether the need to shift, there is no other way to solve! Thank you as much as possible! If you have to do this project also please educated us!
- Since it is installed in the basement of high-rise residential, the transformer must be dry-type transformers. First check the fasteners on the transformer and re-tighten if loosened. Especially the core of the upper and lower clamp, if loose, can not clamp the core noise will be significantly increased. In addition, if the installation of the foot is stable, etc. also check it. Note that the transformer must be de-energized when checking and tightening, and then ground properly. If you really can not reduce the noise of the transformer itself, take sound insulation measures can also have a very significant effect. For example, in the transformer room wall paste sound-absorbing panels. Or install a cushioning rubber pad underneath the foot of the transformer. If you want to achieve better results you can use a special shock absorber to the top of the transformer, so that it does not directly contact the ground. Can play a very good sound insulation effect (using the above sound insulation measures, basically can make the transformer room next door noise reduction 5 ~ 6dB, or even better)
- Q: I got stuck in a problem while solving the previous exam question for my courseTwo transformers with unequal turn ratio and unequal ratings are connected in parallel and have the same secondary voltage. How will the load be distributed between them? Hence find the circulating current.I know how to find the circulating current when the secondary voltages are different. But how can there be a circulating current if the secondary voltage is same?And I know about the load distribution being inversely proportional to the line impedance of the transformers, but what will be the change taking circulating current into account?
- That you may put both the transformers on the same line on their essential aspects however they must have different hundreds at their out places. You ought to use a small load on a 200kva and better load on 500kva. For higher guidance are attempting reffering an electrical engineer near you. I am also an electrical engineer.
- Q: I just finish watching Transformers Revenge of the Fallen for the third time. IT was awesome I 'm getting it on DVD and hoping for it to come out as another transformers.
- Paramount and DreamWorks took the unusual step today of announcing a release date for a movie that had yet to be greenlit. The studios claimed July 1, 2011 as the release date for Transformers 3. Paramount insiders told Variety that they wanted to lock down the July 4th weekend for a third film before another studio claimed the date. But, it's not an official announcement that Transformers 3 is a go. A writer for the third film has not been hired, and it's unknown whether director Michael Bay or stars Shia LaBeouf and Megan Fox would return for the third installment. Transformers 3 might also face a bit of difficulty lining up financing. Paramount managed to shoehorn Transformers 2 into its already completed Melrose II slate deal, but the studio currently has no follow-up long-term co-financing deal that they could use to help cover the costs of a third film. And since General Motors, which has been involved with Transformers and its sequel, might back out of marketing Transformers 2, we doubt they'll be onboard for a third film unless the company's financial condition improves dramatically. Paramount also moved up the release date of Marvel's Thor from June 16, 2011 to May 20, 2011. Considering that Marvel just announced Thor's release date last week and scooped Sony by announcing a release date for Spider-Man 4 at the same time, Paramount's move raises the question: Who sets the release dates for these Marvel productions: Marvel or the distributor?
- Q: I need to know how and auto transformer works and how i can get 240 with it thanks in advance and if theres a website thats explains transformers that would be great (: thnx again !!
- Auto transformer is a single coil wound on a core(iron/ferrite) having three terminals. Out of three, two terminals are fixed on each side. But central terminal is provided in such a manner which can move on the coil from one side to another side. Voltage input is fed across two ends, and output is taken across central point and ground point. Accordingly one end/ common end/ becomes common to both input and output. In some cases, top (phase) terminal, winding is continued further to a tertiary point left open, and variable point moves up to this tertiary point then, in auto transformer only, step up of output is achieved. Please note that input and output voltages can not be isolated in auto transformer. However we same some money since same winding is used common to primary and secondary.
- Q: I am looking into purchasing a counter top coffee roaster that requires a 30 Amp 120 outlet; manufacturer says it uses about 21A.The only plug/circuit that can handle this load at this time is a 240 V outlet. We have a gas stove and we are not currently using the circuit.Does anyone know of a manufacturer that makes a external/freestanding step down (240 to 120) voltage transformer / regulator that I can plug into a grounded (North American) 220V outlet ? Note: a) I don't need it to be variable, just a fixed 240V to 120V is perfect. b)It would also need some sort of internal voltage regulation/ stabilization as erratic voltages would affect the (coffee) roast.
- If each leg of the 240v circuit is 30 amps, you won't need a transformer at all. There are travel kits for going to foreign countries that have a variety of adapters for plugging into 240V outlets that only use one leg of the circuit, which is 120v. Find the adapter that fits your outlet, and you will be up and running! DO NOT TRY TO MAKE SUCH AN ADAPTER YOURSELF UNLESS YOU HAVE A DEGREE IN ELECTRICTY/ELECTRONICS! Using a transformer involves balancing the load, getting a transformer that is rated for the current, a lot of worms in that can. There are also adapters available to stabilize the current, they are available wherever compurers are sold.
- Q: I have a power transformer and i forget where it came from. It has two leads from a wall outlet plug and then goes to the main (square) casing. there are three wires that come out the other side. They are from left to right, red,white and red. I assume its a 9v ac to dc transformer but am not positive. Can someone help me? I suspect that the white wire is ground. Any help would be great.
- There's no reason to assume anything, except that the primary side (with the line cord and plug) is probably intended for 115 Volts, AC. If it's a transformer (rather than a power supply) it's not AC to DC at any voltage. Transformers convert AC to AC. With those colors on the secondary, there's a pretty good chance it's center-tapped. Red-to-red will be twice the voltage of either red-to-white. Nothing should be grounded to the transformer case.
- Q: I live at an apartment complex and I was just returning from work when the entire complex went completely dark. All 12 buildings went offline at the same time, along with the outside lights and the covered parking lights. Since each building has its own transformer, shouldn't they be independent of the others? Why did all 12 buildings and the outside lighting go out together? Are they all on one line or something?
- Are they all on one line or something? Yes. All the transformers likely get power from the same seller. If the transformer are the leaves of a tree then a branch supporting all of them was cut or damaged.
- Q: Transformer tap adjustment there are several ways? What are the advantages and disadvantages?
- 1, no excitation adjustment or no taps. 2, with taps. Their advantages and disadvantages are as follows: 1, no taps: taps when the transformer must be shut down after the power, the advantages of safe and reliable, but the disadvantage is to adjust inconvenient, and often because the tap position can not meet the needs of less. 2, with taps Advantages: easy to adjust, do not have to turn off the transformer power can be adjusted, and the general tap position more easily meet the requirements. Disadvantages: due to load adjustment prone to problems, high cost, compared with the same capacity transformer volume, taps device maintenance needs a long time to blackout.
